a and b started a business jointly a ' s investment was thrice the investment of b and the period of his investment was two times the period of investment of b. if b received rs. 4000 as profit, then their total profit is
multiply(add(multiply(const_2, const_3), const_1), 4000)
"explanation : suppose b invested rs . x for y months . then , a invested rs . 3 x for 2 y months . so , a : b = ( 3 x * 2 y ) : ( x * y ) = 6 xy : xy = 6 : 1 . b ' s profit : total profit = 1 : 7 . let the total profit be rs . x then , 1 / 7 = 4000 / x or x = 28000 . answer : b ) 28000"
