Question
Arvind and Jagdish start a business together. The
capital invested by Arvind was twice of that invested by Jagdish. At the end of six months from the start of the business, Jagdish doubled his investment. If at the end of the year, the total profit earned was Rs. 9100, what was Jagdish’s share from the profit?Solution
Let the capital of Arvind be 2  . And that of Jagdish be Rs.
 . And that of Jagdish be Rs.  Now, the ratio of profits of their share at the end of the year =
 Now, the ratio of profits of their share at the end of the year =  6 + 2
 6 + 2  6 : 2
 6 : 2  12 6
 12 6  + 12
 + 12  : 24
 : 24  18
 18  : 24
 : 24  3
 3  : 4
 : 4  Total profit = 3
 Total profit = 3  + 4
 + 4  = 9100 7
 = 9100 7  = 9100
 = 9100  = Rs. 1300 HenceJagdish’s share of profit = 3
 = Rs. 1300 HenceJagdish’s share of profit = 3  = 3 x 1300 = Rs. 3900
 = 3 x 1300 = Rs. 3900
