Which two numbers (not digits), from the given options, should be interchanged to make the given equation correct?
(48 ÷ 3 + 6) ÷ 11 = 81− 27 ÷ 3 × 5
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 48 and 81.
Given equation: (48 ÷ 3 + 6) ÷ 11 = 81− 27 ÷ 3 × 5
Option 1: 48 and 81
After interchanging the expression becomes:
= (81 ÷ 3 + 6) ÷ 11 = 48 − 27 ÷ 3 × 5
= (27 + 6) ÷ 11 = 48 − 9 × 5
= 33 ÷ 11 = 48 − 45
= 3 = 3
As we have found our answer, there is no need to check further options.
Hence, 48 and 81 is the correct answer.
