Which two numbers (NOT digits) should be interchanged to make the following equation correct?
26 ÷ 2 + 13 × 6−4 = 10
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 2 and 13.
Given equation: 26 ÷ 2 + 13 × 6−4 = 10
Checking all the options one by one:
1. 13 and 4
26 ÷ 2 + 4 × 6−13 = 10
13 + 24 −13 = 10
24 = 10
24 is not equal to 10.
2. 2 and 13
26 ÷ 13 + 2 × 6−4 = 10
2 + 12 − 4 = 10
10 = 10
10 is equal to 10.
The equation is balanced. No need to check other options.
Hence, option 2 is the correct option.
