Krishan and Nandan jointly started a business. Krishan invested three times as Nandan did and invested his money for double time as compared to Nandan. Nandan earned Rs. 4000. If the gain is proportional to the money invested and the time for which the money is invested then the total gain was?
Kishan investment =3N
INVESTMENT PERIOD =2T
EFFECTIVE INVESTMENT = 3N*2T=6NT
6*4000=24000+4000=28000
