Answers
Given:
Cost of 15 cricket bats and 2 tennis bats = 4000
Cost of 10 cricket bats = Cost of 5 tennis bats
To find:
The cost of 12 cricket bats and 2 tennis bats
Calculation:
Let the cost of each cricket bat is x and the cost of each tennis bat is y
Cost of 10 cricket bats = Cost of 5 tennis bats
=> 10x = 5y
y = 2x ……(1)
Cost of 15 cricket bats + Cost of 2 tennis bats = 4000
=> 15x + 2y = 4000
15x + 2(2x) = 4000 [from eq (1)]
19x = 4000
x = Rs 210.52
=> y = 2x
y = 2(210.52)
y = Rs 421.04
The cost of 12 cricket bats and 2 tennis bats = 12x + 2y
= 12(210.52) + 2(421.03)
= Rs 3368.3
The cost of 12 cricket bats and 2 tennis bats is Rs 3368.3
