Two employees X and Y are paid a total of Rs. 570 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 the correct answer:  A) s.259  B) s.289  C) s.299  D) s.300  E) s.389
Let the amount paid to X per week = x   and the amount paid to Y per week = y   Then x + y = 570   But x = 120% of y = 120y/100 = 12y/10   ∴12y/10 + y = 570   ⇒ y[12/10 + 1] = 570   ⇒ 22y/10 = 570   ⇒ 22y = 5700   ⇒ y = 5700/22 = Rs.259   s.259)
