A man engaged a servant on the condition that he would pay him Rs. 90 and a turban after service of one year. He served only for nine months and received the turban and an amount of Rs. 65. The price of turban is:

A. 25

B. 18.75

C. 10

D. 2.50

Answer: Option C

Solution(By Examveda Team)

Let the cost of turban be Rs. x
According to the question
$$\frac{{90 + x}}{{12}} = \frac{{65 + x}}{9}$$     (per month pay)
270 + 3x = 260 + 4x
4x - 3x = 10
x = Rs. 10
