Richa Saini   8 years AGO

Radheshyam invested for 12 months
Let subramanyam invested for 'x' months
Both get equal profit
=> 42000*12=72000*x
Therefore x= 7
So we can say that Subramanyam invested for 7 months.
ie after 5 months Radheshyam invested.
=> Option(4) is the answer.

=>42000 * 12 / 72000 * (12-x)=1/1
=>42000 * 12 = 72000(12-x)
=>84 = 144 - 12x
=>12x = 60
so, x=5
after 5 months subramaniyam joined.
