Example 1:
Joy started a business and he invested in 76000, After some month, amar came to join with him and invest 57000.The end of the year the total profit was divided among them into ratio form 2 : 1.Find after how many months amar join.
Answer :
Step 1: we can assume that amar join into business after x months.So amar money was invest into ( 12 – x ) months.
Step 2: 76000 x 12 / 57000 x ( 12 – x ) = 2 / 1
912000 = 114000 ( 12 – x ) = 114 ( 12 – x ) = 912
= x = 4
After 4 months amar join the business.
Example 2:
Anil, Mukesh and Ritesh started a business each investing Tk.20,000. After 4 month Anil withdraws Rs.6000, Mukesh withdraws Tk.8000, Ritesh invest Tk..6000 more At the end of the years,a total profit was Rs.65600. Find the share of each.
Answer:
Ratio capital of Anil, mukesh and Ritesh.
= ( 20,000 x 4 + 14000 x 8 ) : ( 20,000 x 4 + 12000 x 8 ) : ( 20,000 x 4 + 26000 x 8 )
= 192000 : 176000 : 288000
Anil share = (65600 x 192 / 656 ) = 192000
Mukesh share = ( 65600 x 176 / 656 ) = 176000
Ritesh share = (65600 x 288 / 656 ) = 288000
