SSC CGL 12th April 2022 Shift-3

- Let's consider "M" as the amount of work a man can do in a day, and "B" as the amount a boy can do.

- From the problem: \(5M + 2B\) does the same work in 30 days as \(7M + 10B\) in 15 days.

- Equating the work: \((5M + 2B) \times 30 = (7M + 10B) \times 15\).

- Solve it to find the relation between M and B.

- Use this to calculate how many boys are needed to match the work of 40 men in 4 days.

- Find boys needed with 40 men to do the work in 4 days.

- Option 1: 10

- Option 2: 15

- Option 3: 12

- Option 4: 14

- Correct Answer: Option 1: 10
