SSC MTS 22nd July 2022 Shift-2

- We start with the average of seven numbers being 9. This means the sum of these numbers is \(7 \times 9 = 63\).

- If each number is multiplied by P, the new average becomes 36. Thus, the sum of these new numbers is \(7 \times 36 = 252\).

- The sum after multiplying by P is also \(63 \times P = 252\).

- Solving for P, we divide both sides by 63, giving \(P = \frac{252}{63} = 4\).

Let's review the options:

1. Option:1, 4 - Correct, P = 4.

2. Option:2, 18 - Incorrect.

3. Option:3, 27 - Incorrect.

4. Option:4, 5 - Incorrect.
