two employees a and b are paid a total of rs . 570 per week by their employer . if a is paid 150 percent of the sum paid to b , how much is b paid per week ?
"let the amount paid to a per week = x and the amount paid to b per week = y then x + y = 570 but x = 150 % of y = 150 y / 100 = 15 y / 10 ∴ 15 y / 10 + y = 570 ⇒ y [ 15 / 10 + 1 ] = 570 ⇒ 25 y / 10 = 570 ⇒ 25 y = 5700 ⇒ y = 5700 / 25 = rs . 228 d )"
divide(570, add(divide(150, const_100), const_1))
