p , q and r have rs . 9000 among themselves . r has two - thirds of the total amount with p and q . find the amount with r ?
"let the amount with r be rs . r r = 2 / 3 ( total amount with p and q ) r = 2 / 3 ( 9000 - r ) = > 3 r = 18000 - 2 r = > 5 r = 18000 = > r = 3600 . answer : b"
multiply(divide(9000, add(const_1, divide(const_2, const_3))), divide(const_2, const_3))
