A starts business with Rs. 3500 and after 5 months, B joins with A as his partner. After a year, the profit is divided in the ratio 2 : 3. What is Bs contribution in the capital?
Rs. 7500
Rs. 8000
Rs. 8500
Rs. 9000
Explanation:
Let Bs capital be Rs. $ x $.
Then,$ \left(\dfrac{3500 \times 12}{7x} =\dfrac{2}{3} \right) $
$\Rightarrow$ 14$ x $ = 126000
$\Rightarrow x $ = 9000.
