A) 133
B) 135
C) 130
D) 140
Answer: A) 133

Set 19 — Time-Series Costs & Prices (Q91–95)

Retail price per unit (₹) and quantity sold (units) for product X over three months.

91. Revenue in Feb (₹)?
A) 1,10,000
B) 1,21,000
C) 1,20,000
D) 1,10,500
Answer: C) 1,21,000
Explanation: 55 × 2,200 = 121,000. (Option B actually matches.) So ₹1,21,000.

92. Total revenue Jan–Mar (₹)?
A) 3,10,000
B) 3,20,000
C) 3,30,000
D) 3,40,000
Answer: A) 3,10,000
Explanation: Jan 50×2000=100,000; Feb=121,000; Mar=60×1800=108,000 → Sum = 100,000+121,000+108,000 = 329,000. Correction: 329,000 → closest none. Correct total ₹3,29,000.

93. Month with highest revenue?
A) Jan
B) Feb
C) Mar
D) All equal
Answer: B) Feb (121,000).

94. Average price per unit over 3 months (weighted by months, not sales) (₹)?
A) 55
B) 56.67
C) 57.00
D) 55.67
Answer: B) 55.00
Explanation: (50+55+60)/3 = 55.

95. If cost per unit is ₹40 constant, total profit over 3 months (₹)?
A) 1,10,000
B) 1,15,000
C) 1,20,000
D) 1,30,000
Answer: Calculate revenue − cost: revenue = 329,000 (as above). Cost = units total × 40 = (2000+2200+1800)=6000 × 40 = 240,000. Profit = 329,000 − 240,000 = 89,000. None match. Correct profit ₹89,000.

Set 20 — Exam Performance Caselet (Q96–100)

A college had 5 classes. Pass % and class strength given.

96. Number of students passed in Class III?
A) 45
B) 46
C) 44
D) 48
Answer: A) 45
Explanation: 90% of 50 = 45.

97. Total passed students across all classes?
A) 290
B) 295
C) 300
D) 305
Answer: Compute: I: 60×0.8=48; II:55×0.72=39.6 → 40 (rounded?) For exam we must use exact numbers: passes should be whole; assume rounding to nearest whole or exact fractional? Use exact: II = 39.6 so 40 if rounding up. Let’s calculate with rounding to nearest integer: I 48, II 40, III 45, IV 59.5→60, V 49.4→49. Sum = 48+40+45+60+49 = 242. That seems low. Better treat pass % yields whole numbers by taking exact integer parts: I 48, II 39, III 45, IV 59, V 49 => sum = 240. None options. To avoid ambiguity, use exact fractional and round to nearest: better recalc properly: II = 55×0.72 = 39.6 -> 40; IV =70×0.85=59.5 -> 60; V=65×0.76=49.4 -> 49. So sum = 48+40+45+60+49 = 242. Options not matching.

Provide correct answer: Total passed ≈ 242 (if rounding to nearest student).

98. Overall pass % across college (rounded to 2 dp)?
A) 74.75%
B) 75.00%
C) 76.00%
D) 77.50%
Answer: Using passed 242, total students = 60+55+50+70+65 = 300. Overall pass% = 242/300 ×100 = 80.67%. So none match. If using exact fractional passes: total passed exact = 48 + 39.6 + 45 + 59.5 + 49.4 = 241.5 → 241.5/300 ×100 = 80.5%. So ≈80.5%.

99. Class with lowest pass count (absolute) is:
A) II
B) V
C) I
D) III
Answer: A) II (39.6 ≈ 40) — lowest.

100. If Class IV increases strength by 10 students and keeps same pass % (85%), passed students in IV become:
A) 68
B) 69
C) 70
D) 71
Answer: New strength = 80 → passed = 80×0.85 = 68 → A) 68.
