two employees x and y are paid a total of rs . 800 per week by their employer . if x is paid 120 percent of the sum paid to y , how much is y paid per week ?
"let the amount paid to x per week = x and the amount paid to y per week = y then x + y = 800 but x = 120 % of y = 120 y / 100 = 12 y / 10 ∴ 12 y / 10 + y = 800 ⇒ y [ 12 / 10 + 1 ] = 800 ⇒ 22 y / 10 = 800 ⇒ 22 y = 8000 ⇒ y = 8000 / 22 = rs . 363.63 e )"
divide(multiply(800, multiply(add(const_1, const_4), const_2)), multiply(add(multiply(add(const_1, const_4), const_2), const_1), const_2))
