By interchanging the given two signs ÷ and -, which of the following equations will be correct?
I. 143 + 6 × 18 ÷ 45 − 3 = 236
II. 133 − 7 + 16 × 11 ÷ 37 = 158
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Both I and II.
Given equation:
I. 143 + 6 × 18 ÷ 45 − 3 = 236
II. 133 − 7 + 16 × 11 ÷ 37 = 158
Given condition: ÷ and - are interchanged
I. 143 + 6 × 18 - 45 ÷ 3 = 236
236 = 236
II. 133 ÷ 7 + 16 × 11 - 37 = 158
158 = 158
