The salaries of a and b together amount to rs.2000.a spends 95% of his salary and b, 85% of his salary.if now,their savings are the same what is a's salary

Answer»

Let a's Salary be X
let's salary be y
so x+y=Rs. 2000
implies, x=2000-y   ........ equation 1
out of rs. 100, a SAVES=100-95=rs5
out of rs. x, a saves= x*(5/100) 
similarly, B saves= y*(15/100)
5x/100=15y/100
implies x=3y........ eqn 2
replacing x from eqn to eqn 2

2000-y=3y
4y=2000
y=500
x=1500
a's salary=rs 1500
