Question

Chandru started a business with Rs.42000 and is joined later by Dinesh with Rs.60000. After how many months did Dinesh join if the profits at the end of the year were divided equally?

Answer 1

Answer: $\frac{18}{5}$ months

Step-by-step explanation :

Dinesh's investment = 60,000

Let Dinesh joined after x months.

Thus, He invested his money = (12-x) months.

Now, Chandru invested amount = 42,000

He invested his money = 12 months.

Thus, the ratio of their dinesh's profit and chandru's profit = $\frac{60,000(12-x)}{42000\times 12}$

= $\frac{5(12-x)}{42}$

But According to the question,

The ratio of their profits is 1 : 1

Thus,  $\frac{1}{1}=\frac{5(12-x)}{42}$  

$42=60-5x$  

$5x = 18$

$x=\frac{18}{5}$

Therefore, Dinesh joined after 18/5 months.
