Select the correct combination of mathematical signs to sequentially replace the * signs and balance the given equation.
14 * 1 * 15 * 75 * 21 = 30
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. −, ÷, ×, +.
Given equation: 14 * 1 * 15 * 75 * 21 = 30
Option 1: −, ÷, ×, +
After interchanging the expression becomes:
= 14 − 1 ÷ 15 × 75 + 21 = 30
= 14 − 5 + 21
= 9 + 21
= 30 is equal to 30.
As we have found our answer, there is no need to check further options.
Hence, option 1 is the correct answer.
