Question

What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘-‘ are interchanged and ‘x’ and ‘÷’ are interchanged?
9 – 24 x 3 + 8 ÷ 2 = ?

A.

3

B.

1

C.

2

D.

4

Correct option is B

Interchange the operators as given:
+ ↔ −
× ↔ ÷
Original equation:
9 − 24 × 3 + 8 ÷ 2 = ?
After interchange:
9 + 24 ÷ 3 − 8 × 2 = ?
? = 9 + 24 ÷ 3 − 8 × 2 
? = 9 + 8 − 8 × 2 
? = 9 + 8 − 16
? = 17 − 16
? = 1
Thus, the correct option is: (b)
