Answer 1

ANSWER

Let Vijay's salary = Rs. x

Then Ajay's salary = Rs.(12000−x)

Ajay's savings =(100−80)%=20%,

Vijay's savings =(100−10)%=90%

Since their savings are same,

20% of (12000−x)=10% of x

⇒

100

20

×12000−20% of x=10% of x

⇒30% of x=2400

⇒

100

30

×x=2400

⇒x=

30

2400×100

= Rs. 8000
