Answer»

Solution

Ratio of investments of Raj and Prithvi = $x : (x + 2000)$

TOTAL profit = RS. 8,400

Acc to ques,

=> $\frac{x}{x + x + 2000} \times 8400 = 3600$

=> $\frac{x}{2x + 2000} = \frac{36}{84}$

=> $\frac{x}{2x + 2000} = \frac{3}{7}$

=> $7x = 6x + 6000$

=> $x = 6000$

$\therefore$ Amount INVESTED by Prithvi = 6000 + 2000

= Rs. 8,000
