Question:
The Coach Of a Cricket Team Buys 7 Bats And 6 Balls For Ruppes 3800. Later ,She Buys 3 Bats And 5Balls for Ruppes 1750. Find the Cost of Each Bat And Each Ball.​

Answer 1

Answer:

Cost of bat = Rs 500/-

Cost of ball = Rs 50/-

Step-by-step explanation:

Cost of 7 Bats and 6 Balls = 3800

Let x be the cost of bat and y be the cost of balls

That is

7x + 6y = 3800 ---------------EQN 1

Also its given that

3x + 5y = 1750 _____________EQN 2

ie 1750 - 5y = 3x

ie (1750-5y)/3 = x

Put this value of x in Eqn 1

7 (1750-5y)/3 + 6y = 3800

(12250 - 35y)/3 + 6y = 3800

(12250 - 35y + 18y)/3 = 3800

12250 - 17y = 3 x 3800

12250 - 17y = 11400

12250 - 11400 = 17y

850 = 17y

y = 850/17 = 50 Rs

Cost of ball = Rs 50/-

Put y = 50 in EQN 1

7x + 6 x 50 = 3800

7x + 300 = 3800

7x = 3800-300=3500

x = 3500/7 = 500

Cost of bat = Rs 500.00
