Q1401.A man's basic pay for 40 hours is Rs. 2000. Overtime is paid 25% above basic. If in a week his total wage is Rs. 2500, how many total hours did he work?
Correct Answer: C
Basic rate = 2000/40 = Rs. 50/hour. Overtime rate = 50 * 1.25 = Rs. 62.5/hour. Overtime pay = 2500 - 2000 = Rs. 500. Overtime hours = 500 / 62.5 = 8 hours. Total = 40 + 8 = 48 hours.
Q1402.What is the value of 4/18 + 8/9?
Correct Answer: B
Simplify 4/18 = 2/9. Now: 2/9 + 8/9 = 10/9.
Q1403.What is the value of 2(13 + 10) − 3(14 − 5)?
Correct Answer: B
Evaluate: 2(23) - 3(9) = 46 - 27 = 19.
Q1404.What is 15% of 1000?
Correct Answer: C
Calculated as: 1000 * 0.15 = 150.
Q1405.What is the result of (4 - 4) × 20 + 5?
Correct Answer: B
(4 - 4) * 20 + 5 = 0 * 20 + 5 = 5.
Q1406.What is the 4th multiple of 15?
Correct Answer: C
The 4th multiple of 15 is 15 * 4 = 60.
Q1407.Simplify the exponential expression: a⁴ × a⁸ × a³
Correct Answer: A
When multiplying bases, add the exponents: 4 + 8 + 3 = 15. Thus, the result is a¹⁵.
Q1408.15% of 200 = ?
Correct Answer: C
Calculated as: 200 * 0.15 = 30.
Q1409.What is 1/2 of 1/4 of 1/5 of 200?
Correct Answer: D
Calculated as: (1/2) * (1/4) * (1/5) * 200 = (1/40) * 200 = 5.
Q1410.What is 3/10 divided by 1 4/5?
Correct Answer: B
3/10 ÷ 9/5 = 3/10 * 5/9 = (3*5)/(10*9) = 15/90 = 1/6.
Q1411.What is the value of 2 - 1/3?
Correct Answer: A
Convert to common denominator: 2 = 6/3. Then: 6/3 - 1/3 = 5/3.
Q1412.Evaluate: 2 2/3 × 5/14
Correct Answer: A
Convert mixed fraction: 2 2/3 = 8/3. Multiply: (8/3) * (5/14) = 40/42 = 20/21.
Q1413.What is the value of the division: (9/2) ÷ (81/8)?
Correct Answer: A
(9/2) ÷ (81/8) = (9/2) * (8/81) = (9*8) / (2*81) = 72 / 162 = 4/9.
Q1414.In a triangle puzzle, the first triangle has outer keys 5,3,4 with inner 19. The second has 7,5,6. What is the inner key?
Correct Answer: A
The pattern multiplies the side keys and adds the base: (7 * 5) + 6 = 35 + 6 = 41.
Q1415.What is the mean proportional between 2 and 8?
Correct Answer: B
Let mean proportional be x. Then 2/x = x/8 => x² = 16 => x = √16 = 4.
Q1416.Mr. Rehman spends 1/3 of his salary on personal affairs, gives half of the remaining to his wife, and invests 75% of the final remainder. If he has Rs. 1000 left, what is his total salary?
Correct Answer: C
Let salary = S. Left after personal: 2/3S. Left after wife: 1/3S. Left after investment: 25% of 1/3S = 1/12S. Given 1/12S = 1000 => S = Rs. 12,000.
Q1417.Ismail cycles to work. He takes an average of 40 minutes for a distance of 7 miles. What is his average speed in mph?
Correct Answer: A
Time = 40 mins = 2/3 hours. Speed = Distance / Time = 7 / (2/3) = 7 * 1.5 = 10.5 mph.
Q1418.What is the value of X if: 6 × 4 × 0 × 100 × 0.34 = X?
Correct Answer: D
Since any expression multiplied by zero yields zero, the product of the entire term is 0.
Q1419.What is the average of Kazim's marks: Math=25, Science=20, Urdu=17, English=19?
Correct Answer: C
Average = Sum / Count = (25 + 20 + 17 + 19) / 4 = 81 / 4 = 20.25.
Q1420.If x is the average of k and 15, and y is the average of k and 5, what is the average of x and y in terms of k?
Correct Answer: A
x = (k+15)/2, y = (k+5)/2. Average of x and y = (x+y)/2 = [(2k+20)/2]/2 = (k+10)/2.
