A bat and ball cost Rs. 1.10 and the difference between them is Rs. 1. How much does each cost?
Eq1: Bat + Ball = Rs 1.1 Eq2: Bat - Ball = Rs 1
Adding Eq1 + Eq2 2 Bat = Rs 2.1 i.e. Bat is Rs1.05 which implies ball is Rs .05
x+y=1.10------>eqn1 x-y=1.0------->eqn2 2x=2.10------>by summing up x=1.05---->cost of bat y=.05----->cost of ball
Let, x = Cost of Bat y = Cost of Ball
x - y = 1.00
2y = 0.10
Therefore , y = 0.10/2 = 0.05 x = 1.01-0.05 = 1.05
Now , Bat (x)= 1.05 Ball(y) = 0.05
bat rs 1, ball 0.10
