SSC CPO - 25 Nov 2020 - Shift 1 • Reasoning • Q161

If ‘+ is interchanged with ‘×', and ‘-’ is interchanged with ‘÷', then which of the following equations is correct?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option 2 i.e 18 + 6  x 24 - 4 ÷ 64 = 50​​​​​​.

Given conditions: + → ×; - → ÷

Let us check all the options:

Option 1: 18 - 6 × 24 + 4 ÷ 64 = 50

The expression becomes:

= 18 ÷ 6 + 24 × 4 ÷ 64

= 35 is not equal to 50.

Option 2: 18 + 6 × 24 - 4 ÷ 64 = 50

= 18 × 6 + 24 ÷ 4 - 64

= 50 is equal to 50.

As we have found our answer, there is no need to check other options.

Hence, option 2 is the correct answer.
