Which two symbols from among the given options should be interchanged to make the given equation correct?
(35 – 2) × 3 = (56 × 8 ÷ 3 + 100) × 11
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. × and ÷.
Given equation: (35 – 2) × 3 = (56 × 8 ÷ 3 + 100) × 11
Let us check all the options:
Option 1: ÷ and +
The expression becomes:
= (35 – 2) × 3 = (56 × 8 + 3 ÷ 100) × 11
= 33 × 3 = 448.03 × 11
= 99 is not equal to 4928.33.
Option 2: × and ÷
The expression becomes:
= (35 – 2) ÷ 3 = (56 ÷ 8 × 3 + 100) ÷ 11
= 33 ÷ 3 = 121 ÷ 11
= 11 is equal to 11.
As we have found our answer, so, there is no need to check further options.
Hence, option 2 is the correct answer.
