Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. Only II.

Given: + and ÷

I. 27 ÷ 3 – 18 × 3 + 9 = 24

By interchanging the given two signs:

27 + 3 – 18 × 3 ÷ 9 = 24

27 + 3 - 6 = 24

24 = 24

II. 12 ÷ 8 × 12 + 16 – 7 = 19 

By interchanging the given two signs:

12 + 8 × 12 ÷ 16 – 7 = 19 

12 + 6 - 7 = 19

11 = 19
