Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the equation.
221 * 17 * 12 * 130 * 24 * 50
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. ÷, ×, −, +, =.
Given equation: 221 * 17 * 12 * 130 * 24 * 50
Let us check all the options:
Option 1: ×, ÷, −, +, =
The expression becomes:
= 221 × 17 ÷ 12 - 130 + 24 = 50
= 207.08 is not equal to 50.
Option 2: ÷, ×, −, =, +
The expression becomes:
= 221 ÷ 17 × 12 - 130 = 24 + 50
= 26 is not equal to 74.
Option 3: ÷, ×, −, +, =
The expression becomes:
= 221 ÷ 17 × 12 - 130 + 24 = 50
= 50 is equal to 50.
As we have found our answer, we need not check the other options.
Hence, option 3 is the correct answer.
