Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the equation.
18 * 12 * 4 * 5 * 6 * 53
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e ×, ÷, +, −, =
Option 1: ×, ÷, −, +, =
18 × 12 ÷ 4 − 5 + 6 = 53
18 × 3 – 5 + 6 = 53
54 – 5 + 6 = 53
55 ≠ 53
Option 2: ×, ÷, +, −, =
18 × 12 ÷ 4 + 5 – 6 = 53
18 × 3 + 5 – 6 = 53
54 + 5 – 6 = 53
59 – 6 = 53
53 = 53
Since we got the correct answer from option 2, there is no need to check other options.
Hence, the correct answer is ×, ÷, +, −, =.
