Question: A, S and D Started a business with the investment of TK 5000, TK 4000 and TK 3000 respectively. At the end of the year, the profit received by S and D together is TK 2000 more than the profit received by A. What is the total profit of the business?

Solution:

বিনিয়োগের অনুপাত, A : S : D = 5000 : 4000 : 3000
= 5 : 4 : 3

মনে করি,
মোট লাভ p টাকা
∴ A এর লাভ = 5p/12

S এবং D এর লাভ একত্রে = (4P/12) + (3P/12) = 7p/12

প্রশ্নমতে,
7p/12 = (5p/12) + 2000
or, (7p/12 ) - (5p/12) = 2000
or, (7p - 5p)/12 = 2000
or, 2p/12 = 2000
∴ p = 12000

মোট লাভ 12000 টাকা
