Which two numbers, from among the given options, should be interchanged to make the given equation correct?

$14 + 39 - (\sqrt {144} \div 4) + \left( {5 \times 3} \right) - 6 = 63$

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 4 and 3.

Given equation: $14 + 39 - (\sqrt {144} \div 4) + \left( {5 \times 3} \right) - 6 = 63$

Option 1: 4 and 3

After interchanging the expression becomes:

$14 + 39 - (\sqrt {144} \div 3) + \left( {5 \times 4} \right) - 6 = 63$

14 + 39 - 4 + 20 - 6

63 = 63
