Question
By interchanging the given two numbers (not digits),
which of the following equations will be correct? 24 and 9 I. 113 + 24 – 20 × 9 ÷ 12 = 82 II. 19 × 108 ÷ 9 – 24 + 2 = 200Solution
I. 113 + 24 – 20 × 9 ÷ 12 = 82 113 + 9 – 20 × 24 ÷ 12 = 82 113 + 9 – 20 × 2 = 82 113 + 9 – 40 = 82 82 = 82 II. 19 × 108 ÷ 9 – 24 + 2 = 200 19 × 108 ÷ 9 – 24 + 2 = 200 19 × 12 – 24 + 2 = 200 228 – 24 + 2 = 200 206 ≠ 200
