Question

1. A bat and a ball cost ₹100. If the cost of the bat is ₹20 more than that of the ball, find the
cost of the bat and the ball.
​

Answer 1

Answer:

bat is ₹60, ball is ₹40

Step-by-step explanation:

let the cost of ball be x

and cost of bat is x+20

x+x+20=100

2x=100-20

x=80/2

x=40

the cost of ball is ₹40 and cost of bat is ₹60

Answer 2

Answer:Cost of Bat=₹60 & cost of ball is ₹40

Step-by-step explanation:

Let cost of Bat=X & cost of Ball=y.

According to 1st condition,

x + y =100

then x=100 - y {equation 1}

According to 2nd condition,

20 + y = x {equation 2}

Put x in equation 2,

20 + y = 100-y

2y= 100-20=80

2y = 80 =>y=40

Then put y in equation 2,

x =20+ y => x=20 +40

X= 60
