Sarita started a boutique investing an amount of Rs. 50,000. Six months later Neeta joined her with an amount of Rs. 80,000. At the end of…

Solution
Amount invested by Sarita = Rs. 50,000 and amount invested by Neeta = Rs. 80,000
Ratio of amount invested by Sarita : Neeta = 5 : 8
Time period in which Sarita invested = 12 months and Neeta = 6 months
Ratio of time periods of Sarita : Neeta = 2 : 1
=> Ratio of profits earned by Sarita : Neeta = $(5 \times 2)$:$(8 \times 1)$
= 5 : 4
Total profit earned = Rs. 18,000
$\therefore$ Sarita’s share in the profit = $\frac{5}{(5+4)} \times 18,000$
= $5 \times 2,000 = Rs. 10,000$
=> Ans - (D)
