Answer :

Arun’s initial investment = ₹24000×12


= ₹288000


Later, Arun has invested = ₹12000 more for x months.


= ₹12000x


Arun’s total invrstment = ₹288000 + ₹12000x


Ajoy’s total invrstment = ₹30000×12


= ₹360000


Total profit = ₹14030


Arun’s profit share = ₹7130


Ajoy’s profit share = ₹14030-₹7130


= ₹6900


We know that ratio of profit share is equal to ratio of capital invested.


Ratio of capital invested = Ratio of profit share = 7130:6900


= 713:690




6624 + 276x = 8556


276x = 8556-6624


276x = 1932


X = 7 months


Arun invested money after = 12-7 = 5 months.
