two employees x and y are paid a total of rs . 700 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 = 700 but x = 120 % of y = 120 y / 100 = 12 y / 10 ∴ 12 y / 10 + y = 700 ⇒ y [ 12 / 10 + 1 ] = 700 ⇒ 22 y / 10 = 700 ⇒ 22 y = 7000 ⇒ y = 7000 / 22 = rs . 318.18 e )"
divide(multiply(700, multiply(add(const_1, const_4), const_2)), multiply(add(multiply(add(const_1, const_4), const_2), const_1), const_2))
