Question

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 1

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

Answer 2

Answer:

Step-by-step explanation:

Let the, salary of A=x

salary of B=(2000-x)

According to question-

A spends 95% of x

B spends 85% of (2000-x)

Their savings are-

A = x - (95% Of x)

B = (2000-x) - (85% of (2000-x))

Now, as their savings are same so we can write

x - (95% Of x) = (2000-x) - (85% of (2000-x))........(i)

Solving eq. I

x (1 - 95/100) = (2000-x) (1 - 85/100)

5x = (2000-x)15

20x= 30000

x = 1500

Hence, the salary of A is ₹1500.
