Question

A man bought a horse and a carriage for N3000. He sold the horse at a gain of 20% and the carriage at a loss of 10%, thereby gaining 2% on the whole. Find the cost of the horse.

Answer 1

Answer:

Step-by-step explanation:

Set the cost for horses as x

so the cost of the carriage is 3000 - x

      120%x + 90%(3000 - x) = 102% × 3000

      1.2x + 0.9 × (3000 - x) = 1.02 × 3000

                                x = 1200

∴  the cost of the horse is N1200
