Select the correct combination and order of mathematical signs to replace '*' such that the equation is balanced:
172 * 86 * 14 * 2 = 30
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. ÷, +, x
We check options one by one
Option 1 172 + 86 - 14 ÷ 2 = 172 + 86 - 7 = 172 + 79 = 251 ≠ 30
It is not the correct option
Option 2 172 ÷ 86 + 14 × 2 = 2 + 28 = 30 i.e. it is satisfied the condition.
Hence, this option is correct.
