Question

One year payment to the servant is Rs. 200 plus one shirt. The servant leaves after 9 months and receives Rs.120 and a shirt. The price of the shirt is Rs.___. (Enter 0 in case of Cannot be determined)

Answer 1

At the first glance it seems that the answer is cannot be determined but let’s investigate further. Let the price of the shirt be 12X, where every month he earns ${\frac{1}{12}}^{th}$ of the shirt price plus his wages. He earns $\frac{200}{12}$ every month as salary .. So in 9 months he should've earned 150 cash. But he only got 120 hence Rs.30 went to his shirt deduction.Therefore 3X= 30 $\&$ 12X= 120.
