Solution

The correct option is A
Rs.3000

$\frac{I n v e s t m e n t o f A \times t i m e o f i n v e s t m e n t o f A}{I n v e s t m e n t o f B \times t i m e o f i n v e s t m e n t o f B} = \frac{P r o f i t o f A}{P r o f i t o f B}$

$\frac{I n v e s t m e n t o f A}{I n v e s t m e n t o f B} = \frac{3}{4} I n v e s t m e n t o f A = \frac{3}{7} \times 7000 = R s . 3000$
