a and b put in rs . 300 and rs . 400 respectively into a business . a reinvests into the business his share of the first year ' s profit of rs . 210 where as b does not . in what ratio should they divide the second year ' s profit ?
"3 : 4 a = 3 / 7 * 210 = 90 390 : 400 39 : 40 answer : a"
divide(add(300, multiply(divide(300, add(subtract(400, const_100), 300)), add(210, multiply(const_2, add(const_3, const_2))))), subtract(400, const_100))
