A man invests an amount of Rs 15860 in the name of his three sons Aaryan, Shashank and Yuvi in such a way that they get the same interest after 2, 3 and 4 years respectively. If the rate of simple interest is 5% then what will be the ratio of the amounts invested among Aaryan, Shashank and Yuvi ?
6:4:3
Let the amounts be x, y & z x+y+z=15860 10% of x= 15 % of y = 20 % of z x:y:z=?
2x=3y=4z--> x=2z, y=4/3z x+y+z= 2z+4/3z+z=(6z+4z+3z)/3 the ratio will be 6:4:3 7320+4880+3660=15860 7320*0.1=4880*0.15=3660*0.2=732
