Question

Arun and Vibha started a business by investing Rs 20,000 and Rs 16,000 respectively. After 4 months, Tisha joined them by investing Rs 24,000. Also Arun and Vibha both added Rs 3000. Find the difference in profits of Arun and Tisha if after a year they get Rs 26,880 as profit

Answer 1

Ratio of shares of profit of Arun : Vibha : Tisha,

$\Rightarrow 20000\times 4+23000\times 8:16000\times 4+19000\times 8:24000\times 8$

$\Rightarrow 20+23\times 2:16+19\times 2:24\times 2$

$\Rightarrow 11:9:8$

Total profit earned by them is $26,880$ Rs.

So difference in profits of Arun and Tisha,

$\Rightarrow \frac{11-8}{11+9+8}\times 26880=1880$ Rs.
