12. Arun and Ajoy started a business jointly by investing 24000 and 3 30000 respectively at
the begining of the year. But after a few months Arun invested 12000 more. After a year,
the profit was 14030 and Arun received the profit share of* 7130. Let us find after how many months did does Arun invest money in that business​

Answer 1

Answer:

7 month

Step-by-step explanation:

Arun's investment: 24000

Ajoy's investment: 30000

Arun's further investment: 12000

Profit- 14030; Arun's share- 7130; Ajoy's share= 14030-7130= 6900

Lets see what was the profit share:

6900/30000=0.23

Arun got profit for his initial investment: 0.23*24000=5520

Arun got profit for his further investment: 7130-5520=1610

If further investment was for x month, then:

0.23*x*12000/12=1610

x=12*1610/(12000*0.23)=7 month
