Which two signs and two numbers should be interchanged in the following equation to make it correct?
15 ÷ 80 – 34 + 10 × 8 = 102
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 34, 15, +, ÷.
15 ÷ 80 – 34 + 10 × 8 = 102
After interchanging signs and numbers,
34 + 80 - (15 ÷ 10) × 8 = 102
114 - 3/2 × 8 = 102
114 - 12 = 102
102 = 102.
