135 * 15 * 3 * 2 * 13 *16

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. ÷, ×, +, −, =.

Given equation: 135 * 15 * 3 * 2 * 13 *16

Let us check all the options:

Option 1: ×, +, =, ÷, −

The expression becomes:

= 135 × 15 + 3 = 2 ÷ 13 - 16

= 2028 is not equal to -15.84.

Option 2: =, ×, +, ÷, −

= 135 = 15 × 3 + 2 ÷ 13 - 16

= 135 is not equal to 29.15.

Option 3: +, ÷, −, =, ×

= 135 + 15 ÷ 3 - 2 = 13 × 16

= 138 is not equal to 208.

Option 4: ÷, ×, +, −, =

= 135 ÷ 15 × 3 + 2 - 13 = 16

= 16 is equal to 16.

Hence, option 4 is the correct answer.
