Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. + and −.
Given equation: 272 ÷ 17 − 196 ÷ ( 5 × 3 + 1) = 30
Let us check all the options:
Option 1: + and −
The expression becomes:
= 272 ÷ 17 + 196 ÷ ( 5 × 3 - 1) = 30
= 272 ÷ 17 + 196 ÷ 14
= 16 + 14
= 30 is equal to 30.
As we have found our answer, so, there is no need to check further options.
Hence, option 1 is the correct answer.
