Question
By interchanging the given two numbers (not digits),
which of the following equations will be correct? 44 and 19 I. 203 + 44 – 27 × 19 ÷ 11 = 114 II. 9 × 572 ÷ 19 – 44 + 4 = 120Solution
I. 203 + 44 – 27 × 19 ÷ 11 = 114 203 + 19 – 27 × 44 ÷ 11 = 114 203 + 19 – 27 × 4 = 114 203 + 19 – 108 = 114 114 = 114 II. 9 × 572 ÷ 19 – 44 + 4 = 120 9 × 572 ÷ 44 – 19 + 4 = 120 9 × 13 – 19 + 4 = 120 117 – 19 + 4 = 120 102 ≠120
