Question

cost of 13 bats and 31 balls is Rs 4900. What of 11 bats and 20 balls, if cost of 1 bats is Rs 170​

Answer 1

Step-by-step explanation:

cost of 13 bats &31 balls= 4900

cost of 1 bat = 170

so, 13 ×170= 2210.

therefore, 4900-2210=2690

cost of 31 balls = 2690

cost of 1 ball = 2690/31

= 86.7

cost of 11 bats = 170×11

=1870

cost of 20 balls =86.7× 20

=1734

cost of 11 bats and 20 balls =3604

hope it is helpful.
