Q12 of 62 Page 121

Amit was given an increment of 20% on his salary. If his new salary is Rs. 30600, what was his salary before the increment?

Let Amit’s old salary = Z


∴ Salary after increment = (Z + 20Z/100)


Now,


⇒ (Z + 20 Z/100) = 30600


⇒ (100 Z + 20 Z)/100 = 30600


⇒ 120 Z = 30600 × 100


⇒ Z = 25500
