Question

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

Answer 1

Answer:

Let , cost of 1 bat is x

        cost of 1 ball is y

From your question,

       The two equation are :

        7x + 6y = 3800 -------------------------------------- (i)

         3x + 3y = 1750  or x + y = 1750/3 ---------------------------------------(ii)

From equation (ii) ,

         => 3x + 3y = 1750  

         => 3x = 1750 - 3y

         => x =  (1750 - 3y) / 3

by putting the value of x in equation (i)

      We get,

     => 7 [  (1750 - 3y) / 3 ] + 6y = 3800

     => 12250/3 -7y + 6y = 3800

     => y = ₹ 283.34 ( Ball )

Putting the value of y in equation (ii) ,

     => x + 283.34 = 1750

     => x = ₹ 1466.66 ( Bat )

         Hope it helps
