Ravi and rashmi invested 150and 200 respectively in a business but Ravi withdrew his money after a few months if the end of twelve month profit shared between Ravi and rashmi in the ratio 1:2 after how many month did Ravi take out his money

Answer 1

Investment by Ravi = 150
Time period of Investment of Ravi = let t months

Investment by Rashmi = 200
Time period of Investment of Rashmi = 12 months

Ratio of Investment will be given by amount invested in respective months
150(t) : 200(12)
150t : 2400
3t : 48 
t : 16
Now, this ratio of investment will be equal to the ratio of profit divided among them
Ratio of profit = Ratio of Investment
1:2 = t:16
1/2 = t/16
t = 8
Therefore, Ravi withdrew his money after 8 months.
