Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the given equation.
25 * 48 * 6 * 12 * 2 = 41
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2. i.e. −, ÷, +, ×.
Given equation: 25 * 48 * 6 * 12 * 2 = 41
Option 1: −, ×, +, ÷
After interchanging the expression becomes:
= 25 − 48 × 6 + 12 ÷ 2 = 41
= 25 − 48 × 6 + 6
= 25 - 288 + 6
= -257 is not equal to 41.
Option 2: −, ÷, +, ×
After interchanging the expression becomes:
= 25 − 48 ÷ 6 + 12 × 2 = 41
= 25 − 8 + 12 × 2
= 25 - 8 + 24
= 41 is equal to 41.
As we have found our answer, there is no need to check further options.
Hence, option 2 is the correct answer.
