rs . 700 is divided among a , b , c so that a receives half as much as b and b half as much as c . then c ' s share is
"let c = x . then b = x / 2 and a = x / 4 a : b : c = 1 : 2 : 4 . c ' s share rs . [ ( 4 / 7 ) * 700 ) = 400 answer : c"
multiply(divide(const_4, add(const_4, add(const_1, const_2))), 700)
