What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘-‘ are interchanged and ‘×’ and ‘÷’ are interchanged?
56 - 33 × 3 ÷ 4 + 36 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 64.
Given equation: 56 - 33 × 3 ÷ 4 + 36 = ?
After interchanging the signs:
56 + (33 ÷ 3) × 4 - 36 = ?
= 56 + (11 × 4) - 36
= 56 + 44 - 36
= 100 - 36
= 64
