Question

Forty horses are bought for Rs. 15,000. The average cost of fifteen of them is Rs. 300. What is the
average cost of others?

Answer 1

Answer:

Total cost of 40 horses = Rs 15000

Average cost of 15 of the horses = Rs 300

Total cost of 15 horses = 300 * 15 = Rs 4500

Total cost of other 25 horses = 15000 - 4500

= Rs 10500.

Average cost for 25 horses = 10500/25 = Rs 420.
