Select the correct combination of mathematical signs to replace the * signs and to balance the given equation.
23 * 12 * 36 * 2 * 9 * 285
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. ×, +, ÷, –, =.
Given equation: 23 * 12 * 36 * 2 * 9 * 285
Option 1: –, =, ×, ×, ÷
After interchanging the expression becomes:
= 23 - 12 = 36 × 2 × 9 ÷ 285
= 11 = 2.273
= 11 is not equal to 2.273.
Option 2: ×, +, ÷, –, =
After interchanging the expression becomes:
= 23 × 12 + 36 ÷ 2 - 9 = 285
= 23 × 12 + 18 - 9
= 276 + 18 - 9
= 285 is equal to 285.
As we have found our answer, there is no need to check further options.
Hence, option 2 is the correct answer.
