Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the given equation.
12 * 70 * 5 * 5 * 5 * 11 * 2
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. +, –, ×, =, ×, +.
Given equation: 12 * 70 * 5 * 5 * 5 * 11 * 2
Option 1: +, –, ×, =, ×, +
After interchanging the expression becomes:
= 12 + 70 – 5 × 5 = 5 × 11 + 2
= 12 + 70 – 25 = 55 + 2
= 82 - 25 = 57
= 57 = 57
Hence, +, –, ×, =, ×, + is the correct answer.
