Two employees Y and Z are paid a total of Rs. 550 per week by their employer. If Y is paid 120 percent of the sum paid to Z, how much is Z paid per week?
Choose the correct option
A) A)Rs.200 B) B)Rs.220 C) C)Rs.250 D) D)Rs.300 E) E)Rs.350
Let the amount paid to Y per week = y   and the amount paid to Z per week = z   Then x + y = 550   But y = 120% of z = 120z/100 = 12z/10   ∴12z/10 + z = 550   ⇒ z[12/10 + 1] = 550   ⇒ 22z/10 = 550   ⇒ 22z = 5500   ⇒ z = 5500/22 = 500/2 = Rs.250   Rs.250
