Which two numbers, from the given options, should be interchanged to make the given equation correct?
95 ÷ 19 × 112 ÷ (4 × 4 + 3) + 5 = 24
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 4 and 5.
Given equation: 95 ÷ 19 × 112 ÷ (4 × 4 + 3) + 5 = 24
Option 1: 112 and 95
After interchanging the expression becomes:
= 112 ÷ 19 × 95 ÷ (4 × 4 + 3) + 5 = 24
= 112 ÷ 19 × 95 ÷ 19 + 5
= 112 ÷ 19 × 5 + 5
= 34.57 is not equal to 24.
Option 2: 4 and 5
After interchanging the expression becomes:
= 95 ÷ 19 × 112 ÷ (5 × 5 + 3) + 4 = 24
= 95 ÷ 19 × 112 ÷ 28 + 4
= 5 × 4 + 4
= 24 is equal to 24.
As we have found our answer, there is no need to check further options.
Hence, 4 and 5 is the correct answer.
