Two employees X and Y are paid a total of Rs. 500 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 choice from the following answers:
A) s.227  B) s.287  C) s.297  D) s.300  E) s.380
Let the amount paid to X per week = x   and the amount paid to Y per week = y   Then x + y = 500   But x = 120% of y = 120y/100 = 12y/10   ∴12y/10 + y = 500   ⇒ y[12/10 + 1] = 500   ⇒ 22y/10 = 500   ⇒ 22y = 5000   ⇒ y = 5000/22 = Rs.227.77   s.227)
