What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘ב are interchanged and ‘-’ and ‘÷’ are interchanged?
18 ÷ 90 - 5 × 11 + 2 =?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 22.
Given equation: 18 ÷ 90 - 5 × 11 + 2 =?
After interchanging the signs:
18 - (90 ÷ 5) + 11 × 2 =?
= 18 - 18 + (11 × 2)
= 18 - 18 + 22
= 40 - 18
= 22
