An old lady engaged a domestic help on the condition that she would pay him Rs. 90 and a gift after service of one year. He served only 9 months and received the gift and Rs. 65. Find the value of the gift.
Explanation:
Let the price of the gift be x.
Hence, total value to be paid to domestic help for one year = 90 + x
∴ Value of domestic help for 9 months = 3/4 × (90 + x) ∴ 65 + x = 3/4 × (90 + x) ∴ x = 10
Hence, option (a).
