Two employees A and B are paid a total of Rs. 450 per week by their employer. If A is paid 150 percent of the sum paid to B, how much is B paid per week?  Choices.
A) 130  B) 140  C) 150  D) 170  E) 180
Let the amount paid to A per week = x   and the amount paid to B per week = y   Then x + y = 450   But x = 150% of y = 150y/100 = 15y/10   ∴15y/10 + y = 450   ⇒ y[15/10 + 1] = 450   ⇒ 25y/10 = 450   ⇒ 25y =4500   ⇒ y = 4500/25 =Rs.180   180
