What will come in the place of ‘?’ in the following equation if ‘+’ and ‘×’ are interchanged and ‘-’ and ‘÷’ are interchanged?
90 - 10 × 36 + 52 ÷ 49 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 1832.
Given equation: 90 - 10 × 36 + 52 ÷ 49 = ?
After interchanging the expression becomes:
= (90 ÷ 10) + 36 × 52 - 49
= 9 + (36 × 52) - 49
= 9 + 1872 - 49
= 1881 - 49
= 1832
