Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 16 and 20, – and +.
Given equation: 240 ÷ 20 – 16 × 14 + 120 = 175
On interchanging the signs and numbers:
240 ÷ 16 + 20 × 14 - 120 = 175
15 + 20 × 14 - 120 = 175
15 + 280 - 120 = 175
295 - 120 = 175
175 = 175
