Question

The coach of a cricket team buys 7 bats and 6 balls for ₹ 3800. Later she buys 3 bats and 5 balls for ₹1750. Find the cost of each bat and each ball.​

Answer 1

Answer:

cost of 1 ball = x

cost of q vat =y

then ATQ

6x+7y=3800_____(i)

5x+3y=1750______(ii)

now multiplying (i) eqn by 5 and (ii) by 6

(6x+7y=3800)×5 = 30x+35y=19000

(5x+3y=1750)×6 = 30x+18y=10500

now subtracting them

17y= 8500

y=500

now putting value of y in equation (i)

6x+7y=3800

6x+7(500)=3800

6x+3500=3800

6x=300

x=50

so cost of one bat = 500

and one ball = 50
