Two employees X and Y are paid a total of Rs. 528 per week by their employer. If X is paid 120 percent of the sum paid to Y, how much is Y paid per week?	Choose one.
A) s.250 B) s.280 C) s.290 D) s.299 E) s.240
Let the amount paid to X per week = x   and the amount paid to Y per week = y   Then x + y = 528   But x = 120% of y = 120y/100 = 12y/10   ∴12y/10 + y = 528   ⇒ y[12/10 + 1] = 528   ⇒ 22y/10 = 528   ⇒ 22y = 5280   ⇒ y = 5280/22 = 480/2 = Rs.240   s.240
