What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘× ‘ are interchanged and also ‘-’ and ‘ ÷’ are interchanged?
1 × 14 + 30 − 20 ÷ 10 =?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 12.
Given equation is: 1 × 14 + 30 − 20 ÷ 10 =?
If 'x' and '+' are interchanged and ‘-’ and ‘ ÷’ are interchanged, the equation becomes:
1 + 14 × 30 ÷ 20 - 10
= 1 + 21 - 10
= 12
Hence, option 4 is the correct option.
