Problem: a , b and c start a business each investing 20,000 . after 10 months a withdrew 5000 , b withdrew 4000 and c invests 6000 more . at the end of the year , a total profit of 71400 was recorded . find the share of b .
Rationale: "ratio of the capitals of a , b and c = 20000 ã — 10 + 15000 ã — 2 : 20000 ã — 10 + 16000 ã — 2 : 20000 ã — 10 + 26000 ã — 2 = 230000 : 232000 : 252000 = 230 : 232 : 252 . b â € ™ s share = ( 71400 ã — 232 â  „ 714 ) = 23200 ; answer c"
