(Note: Interchange should be done of entire number and not individual digits of a given number)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 3 and 2.
Given equation: 50 × 3 + 12 × 5 – (66 ÷ 2) + 11 × 4 – 22 = 160
After interchanging the digits:
50 × 2 + 12 × 5 – (66 ÷ 3) + 11 × 4 – 22 = 160
100 + 60 - 22 + 44 - 22 = 160
204 - 44 = 160
160 = 160
