Shekhar started a business investing Rs. 25,000 in 1999. In 2000, he invested an additional amount of Rs. 10,000 and Rajeev joined him with an amount of Rs. 35,000. In 2001, Shekhar invested another additional amount of Rs. 10,000 and Jatin joined them with an amount of Rs. 35,000. What will be Rajeev's share in the profit of Rs. 1,50,000 earned at the end of 3 years from the start of the business in 1999 ?

A) 50000

B) 40000

C) 25000

D) 15200

$=(25000\times 12+35000\times 12+45000\times 12)$ $:(35000\times 24)$ $:(35000\times 12)$
$= 1260000:840000:420000$ $= 3:2:1$.
Rajeev's share = Rs. $\left(150000\times \frac{2}{6}\right)$ = Rs. 50000.
