Question

the salary of a person was reduced by 40%.By what % should his salary be raised so as to bring it at par with his original salary

Answer 1

the salary must be increased by 70% from the reduced salary to make it par with his original salary

Answer 2

Answer:

His salary must be increased by 66.67%

Step-by-step explanation:

Let his original salary be 100x and the percentage by which the reduced salary must to be increased n.

The reduced salary is 60x.

So (100 +n)% of 60x is 100x.

$\frac{100+n}{100}$ = $\frac{100x}{60x}$

= $\frac{5}{3}$

3(100 + n) = 5(100)     (by cross multiplication)

3n = 500 - 300 = 200

n  = $\frac{200}{3}$ = 66.67
