Which two numbers (not digits) should be interchanged to make the given equation correct?
72 – 6 + (18 ÷ 4) + 17 – (22 × 2) = 44

Correct option is D

Given - 72 – 6 + (18 ÷ 4) + 17 – (22 × 2) = 44

option a 2 and 4
72 – 6 + (18 ÷ 2) + 17 – (22 × 4) = 44
72 - 6 + 9 + 17 - 88 = 44
98 - 94 = 44
4 is not equal to 44
option b; 22 and 18
72 – 6 + (22 ÷ 4) + 17 – (18 × 2) = 44
72 - 6 + 5.5 + 17 - 36 = 55
it will give decimal number which is not equals to RHS
option c; 6 and 22
72 – 22 + (18 ÷ 4) + 17 – (6 × 2) = 44
72 - 22 + 4.5 + 17 - 12 = 44
it will give decimal number which is not equals to RHS
option d; 6 and 4
72 – 4 + (18 ÷ 6) + 17 – (22 × 2) = 44
72 - 4 + 3 + 17 - 44 = 44
92 - 48 = 44
44 = 44
hence option d is correct option.
