31. If 6 persons working 8 hours a day earn Rs.8400 per week, then how much will 9 persons working 6 hours a day each per week?

Check answer and explanation

Answer: Rs.9450

Explanation 6 persons working 8 hours a day earn Rs. 8400 per week. First, let's calculate the total hours worked by 6 persons in a week: 6 persons x 8 hours/day x 7 days/week = 336 hours/week Now, let's calculate the total amount earned per hour: Rs. 8400 per week ÷ 336 hours/week = Rs. 25 per hour Now, let's calculate the total hours worked by 9 persons in a week: 9 persons x 6 hours/day x 7 days/week = 378 hours/week Finally, let's calculate the total amount earned by 9 persons in a week: 378 hours/week x Rs. 25 per hour = Rs. 9450 per week So, the correct answer is: Rs. 9450

32. Three persons A, B, C invested an amount of 12 lac Rupees ratio 2:3:5. What is the investment amount of person A?

Explanation Total ratio parts = 2 + 3 + 5 = 10 A's ratio = 2 A's investment = (2/10) × 12 lac = 2.4 lac Last verified on 15-03-2026

33. The mean proportional of 4 and 16 is ______?

Check answer and explanation

Answer: 8

Explanation The mean proportional of two numbers is the square root of their product. Mean proportional = √(4 × 16) = √64 = 8

34. If a : b = 4 : 5 and b : c = 3 : 2, then a : c equals?

Check answer and explanation

Answer: 6:5

Explanation Make b the same in both ratios: a : b = 4 : 5 = 12 : 15 b : c = 3 : 2 = 15 : 10 So a : b : c = 12 : 15 : 10 Therefore a : c = 12 : 10 = 6 : 5 Last verified on 07-05-2026

35. 3:5 is equal to which fraction?

Check answer and explanation

Answer: 30:50

36. If 25 workers can complete a task in 30 days, the number of workers required to complete the task in 15 days is _____?

Check answer and explanation

Answer: 50

Explanation Let's solve this inverse proportion problem. 25 workers × 30 days = x workers × 15 days x = (25 × 30) / 15 x = 50

37. Sara has 5 red marble, 3 green marbles and 2 blue marbles. What fraction of the marbles are green?

Check answer and explanation

Answer: 3/10

Explanation To find the fraction of green marbles , we need to calculate the total number of marbles first. Sara has: - 5 red marbles - 3 green marbles - 2 blue marbles Total marbles = 5 (red) + 3 (green) + 2 (blue) = 10 marbles Next, we determine the fraction of green marbles out of the total marbles: Fraction of green marbles = Number of green marbles / Total number of marbles Fraction of green marbles = 3 / 10

38. Divide 180 rupees among A, B, and C in the ratio 2:3:4, B will get _____?

Check answer and explanation

Answer: 60

Explanation Sum of ratio parts = 2 + 3 + 4 = 9 Each part = 180 ÷ 9 = 20 B's share (3 parts) = 3 × 20 = 60

39. If 40% of a number is equal to two-third of another number. What is the ratio of first number to the second number?

Check answer and explanation

Answer: 5:3

Explanation Given that 40% of a number is equal to two-third of another number, we need to find the ratio of the first number to the second number. Let's assume that the first number is x and the second number is y. 40% of x is equal to 2/3 of y. We can write this as: 0.4x = 2/3 y To find the ratio of x to y, we can divide both sides by y: 0.4x/y = 2/3 Simplifying further, we get: x/y = (2/3)/(0.4) x/y = 5/3 Therefore, the ratio of the first number to the second number is 5:3.

40. If A : B = 3 and B : C = 1 : 2 then A : B : C is?

Check answer and explanation

Answer: 3 : 5 : 10

Explanation Given: A : B = 3 : 1 and B : C = 1 : 2. To find A : B : C, make the ratio of B the same in both expressions. A : B = 3 : 1 means A = 3B. B : C = 1 : 2 means C = 2B. So, A : B : C = 3B : B : 2B, which simplifies to 3 : 1 : 2. Now, multiply the entire ratio by 5 to make the B value in all ratios equal: 3 : 5 : 10.
