Hi Candidate,

Three people X, Y, and Z have to get a 5 percentage of interest upon their capital investment, and the extra money they get through investing is termed as profit.

X has a capital of 20,000 on which he gets a 5% interest= 5/100*20000= 1000. Y has a capital of 10,000 and 5% intrest= 500. Z has a capital of 4000 with 5% interest= 200. So, the total profit earned by three of them= 1000+500+200= 1700.

Hope that this answer helps you!!
