StudyBix

Solution 81: Option B (has been reading)

Explanation:

Step 1: The active sentence is in Simple Past tense (Subject + V2 + Object). The passive voice structure for this is: Object + was/were + V3 (past participle) + by + Subject. Hence, 'She ate an apple' becomes 'An apple was eaten by her.'

StudyBix

Solution 87: Option B (A movie is being watched by us.)

Explanation:

Step 1: The active sentence is in Present Continuous tense. The passive structure is: Object + is/am/are + being + V3 + by + Subject. Therefore, 'We are watching a movie' becomes 'A movie is being watched by us.'

StudyBix

Solution 88: Option A (She said that she was cooking.)

Explanation:

StudyBix

Solution 89: Option D (He asked her why she was late.)

Explanation:

Step 1: For interrogative sentences starting with a WH-word, the reporting verb 'said to' changes to 'asked'. The WH-word acts as the conjunction. The sentence structure becomes affirmative: 'Subject + Verb'. Thus, 'why are you late?' becomes 'why she was late.'

StudyBix

Solution 90: Option C (little)

Step 3: Percentage = (50 / 200) × 100 = (1/4) × 100 = 25%.

StudyBix

Solution 104: Option B (15:12:8)

Explanation:

Step 1: We are given A:B = 5:4 and B:C = 3:2. Notice that the value of B is 4 in the first ratio and 3 in the second.

Step 2: To combine them, find the LCM of 4 and 3, which is 12. Multiply the first ratio by 3: A:B = 15:12.

Step 3: Multiply the second ratio by 4: B:C = 12:8. Now combining them gives A:B:C = 15:12:8.

StudyBix

Solution 105: Option B (30)

Explanation:

Step 1: Here, Cost Price (CP) = Rs 3000 and Selling Price (SP) = Rs 3600. The total Profit = SP - CP = 3600 - 3000 = Rs 600.

Step 2: The formula for Profit Percentage is: (Profit / CP) × 100.

Step 3: (600 / 3000) × 100 = (1/5) × 100 = 20%.

Solution 109: Option B (Rs 450)

Explanation:

Step 1: Let the Cost Price (CP) be x. A 20% profit means the Selling Price (SP) is 120% of the Cost Price. So, 1.2x = 540.

Step 2: Alternatively, use the direct formula: CP = [100 / (100 + Profit%)] × SP.

Step 3: CP = (100 / 120) × 540 = (5/6) × 540 = 5 × 90 = Rs 450.

Solution 110: Option D (5% per annum)

Explanation:

Step 1: The formula for Simple Interest is: SI = (P × R × T) / 100, where P=Principal, R=Rate, T=Time.

Step 2: Substitute the given values: 1000 = (5000 × R × 4) / 100.

Step 3: Simplify: 1000 = 200 × R. Therefore, R = 1000 / 200 = 5%.

Solution 111: Option A (12 days)

Explanation:

Step 1: Use the inverse proportion formula for Time and Work: M1 × D1 = M2 × D2 (where M=Men, D=Days).

Step 2: We are given M1 = 8, D1 = 15, and M2 = 10.

Step 3: 8 × 15 = 10 × D2 => 120 = 10 × D2. Therefore, D2 = 120 / 10 = 12 days.

Solution 112: Option B (3 hours)

Explanation:

Step 1: The relationship between Time, Distance, and Speed is defined by the formula: Time = Distance ÷ Speed.

Step 2: Given Distance = 45 km and Speed = 15 km/h.

Step 3: Time = 45 ÷ 15 = 3 hours.

Solution 113: Option C (150 sq cm)

Explanation:

Step 1: The formula for the perimeter of a rectangle is: 2 × (Length + Breadth). We know Perimeter = 50 and Breadth = 10.

Step 2: 2 × (L + 10) = 50 => L + 10 = 25 => L = 15 cm.

Step 3: Area of a rectangle = Length × Breadth = 15 × 10 = 150 sq cm.

StudyBix

Solution 114: Option B (36 cm)

Explanation:

Step 1: The area of a square is calculated as: Side². Here, Side² = 81, which means Side = √81 = 9 cm.

Step 2: The perimeter of a square is given by the formula: 4 × Side.

Step 3: Perimeter = 4 × 9 = 36 cm.

StudyBix

Solution 115: Option D (616 sq cm)

Explanation:

Step 1: The area of a circle is calculated using the formula: Area = π × r². Here, r = 14 cm.

Step 2: Substitute the values: Area = (22/7) × 14 × 14.

Step 3: Simplify: 22 × 2 × 14 = 44 × 14 = 616 sq cm.

StudyBix

Solution 116: Option B (128)

Explanation:

Step 1: Analyze the logic of the given number series. Each number is exactly double the previous number.

Step 2: 4 × 2 = 8; 8 × 2 = 16; 16 × 2 = 32; 32 × 2 = 64.

Step 3: Following this pattern, the next number will be 64 × 2 = 128.

StudyBix

Solution 117: Option B (50)

Explanation:

Step 1: Observe the common difference between the consecutive numbers in the series.

Step 2: 90 - 10 = 80; 80 - 10 = 70; 70 - 10 = 60. The series decreases by exactly 10 at each step.

Step 3: The next number will naturally be 60 - 10 = 50.

StudyBix

Solution 118: Option C (S)

Explanation:

Step 1: Analyze the English alphabet positions. The series skips exactly two letters to get the third letter forward (+3 pattern).

Step 2: D (+3) = G; G (+3) = J; J (+3) = M; M (+3) = P.

Step 3: Adding 3 steps forward from P yields S (P -> Q -> R -> S).

StudyBix

Solution 119: Option A (K)

Explanation:

Step 1: Observe the reverse alphabet positions. The series steps backward by exactly 3 letters at a time (-3 pattern).

Step 2: Z (-3) = W; W (-3) = T; T (-3) = Q; Q (-3) = N.

Step 3: Moving 3 steps backward from N yields K (N -> M -> L -> K).

StudyBix

Solution 120: Option C (RVFFO)

Explanation:

Step 1: Decode the pattern in 'KING' -> 'LJOH'. Notice that each letter is shifted forward by exactly one position (+1). K->L, I->J, N->O, G->H.

Step 2: Apply the same +1 shift logic to 'QUEEN'.

Step 3: Q->R, U->V, E->F, E->F, N->O. Thus, the coded word is RVFFO.

StudyBix

Solution 121: Option C (6-2-4)

Explanation:

Step 1: Identify the standard alphabetical positions: A=1, B=2, C=3.

Step 2: The coding rule doubles each numerical position: A (1×2)=2, B (2×2)=4, C (3×2)=6.

Step 3: For 'CAB', substitute the doubled codes: C=6, A=2, B=4. Hence, the code is 6-2-4.

StudyBix

Solution 122: Option C (Planet)

Explanation:

Step 1: Understand the primary relationship in the first pair. The 'Moon' is scientifically classified as a natural 'Satellite'.

Step 2: Apply the exact same classification logic to the second subject. 'Earth' is classified as a 'Planet' revolving around the Sun.

StudyBix

Solution 123: Option D (Cold)

Explanation:

Step 1: This analogy explores the inherent defining physical property of the first object. The fundamental property of 'Fire' is that it is 'Hot'.

Step 2: By applying the same logic, the inherent and defining physical property of 'Ice' is that it is 'Cold'.

StudyBix

Solution 124: Option A (Clothes)

Explanation:

Step 1: Analyze the function of the container. A 'Library' is primarily a designated place intended to hold and store 'Books'.

Step 2: Similarly, a 'Wardrobe' is a piece of furniture expressly designed to hold, store, and organize 'Clothes'.

StudyBix

Solution 125: Option C (Water)

Explanation:

Step 1: Evaluate the underlying category of the listed items. Table, Chair, and Bench are all solid objects classified as household furniture, typically made of wood or plastic.

Step 2: 'Water', on the other hand, is a naturally occurring liquid substance and does not belong to the furniture category, making it the odd one out.

StudyBix

Solution 126: Option B (9)

Explanation:

Step 1: Look closely at the mathematical properties of the numbers in the series: 2, 3, 5, 7. All of these are prime numbers (they are divisible only by 1 and themselves).

Step 2: The number 9 is a composite number (divisible by 1, 3, and 9). Therefore, 9 breaks the prime number sequence and is the odd one out.

Solution 127: Option D (Grandfather)

Explanation:

Step 1: Break the blood relation down step by step starting from 'your'. Your mother's husband is biologically 'your father'.

Step 2: Now, taking the next step in the sentence: your father's father is your 'Grandfather' (specifically, paternal grandfather).

StudyBix

Solution 128: Option D (Mother)

Explanation:

Step 1: Based on the statement, Y and Z are siblings because Y is explicitly stated as the brother of Z.

Step 2: Since X is the mother of Y, and Y and Z share the same parentage, X naturally must also be the mother of Z.

StudyBix

Solution 129: Option B (13 km)

Explanation:

Step 1: The person moves 5 km East. A left turn from East points him toward the North direction, where he walks exactly 12 km.

Step 2: This movement creates a right-angled triangle where the Base = 5 km and Perpendicular = 12 km. The shortest distance is the Hypotenuse.

Step 3: Using Pythagoras theorem: Distance = √(5² + 12²) = √(25 + 144) = √169 = 13 km.

Solution 130: Option A (West)

Explanation:

Step 1: Imagine standing on a standard compass rose facing directly North (0 degrees).

Step 2: Making a 90-degree turn to your left (anti-clockwise) instantly changes your heading to point straight toward the West.

StudyBix

Solution 131: Option B (Circle B is inside Circle A, and Circle C is completely separate)

Explanation:

Step 1: Since "all whales are mammals", Circle B (Whales) must be drawn entirely inside Circle A (Mammals).

Step 2: Because "no whale or mammal is a fish", Circle C (Fishes) will share no common area with A or B and must be drawn completely separate from them.

StudyBix

Solution 132: Option C (Two disjoint circles inside a larger circle)

Explanation:

Step 1: Violinists and Pianists are entirely distinct professions ("no violinist plays the piano"), so their circles do not touch or overlap (they are disjoint).

Step 2: However, since both groups are collectively 'Musicians', both of these disjoint circles must reside completely inside the larger main circle representing 'Musicians'.

StudyBix

Solution 133: Option D (WOW)

Explanation:

Step 1: The capital letters 'W' and 'O' are perfectly symmetrical along their vertical axis. Therefore, their mirror images look completely identical to the original letters.

Step 2: Because the word itself spells 'WOW', the entire word reversed left-to-right remains 'WOW'.

StudyBix

Solution 134: Option B (4)

Explanation:

Step 1: A standard triangular pyramid, also known formally as a tetrahedron, has a triangular base (which gives it 3 corners).

Step 2: All three base corners connect up to a single top point (the apex). Therefore, the total number of corners (vertices) is 3 + 1 = 4.

StudyBix

Solution 135: Option C (I)

Explanation:

Step 1: A water image involves flipping an object upside down (top-to-bottom inversion).

Step 2: The capital English letter 'I' exhibits perfect horizontal symmetry (the top half is a mirror image of the bottom half). Hence, flipping it upside down results in the exact same shape 'I'.
