Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation.
30 * 2 * 20 * 13 * 67
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. ×, +, –, =.
Given equation: 30 * 2 * 20 * 13 * 67
Option 1: ×, –, +, =
After interchanging the expression becomes:
= 30 × 2 – 20 + 13 = 67
= 60 – 20 + 13
= 53 is not equal to 67.
Option 2: ×, +, –, =
After interchanging the expression becomes:
= 30 × 2 + 20 – 13 = 67
= 60 + 20 – 13
= 67 is equal to 67.
As we have found our answer, there is no need to check further options.
Hence, ×, +, –, = is the correct answer.
