Question: Aysha and Jara started a business by investing Tk. 85000 and Tk. 15000 each. What be will the ratio of profit earned after 2 years between Aysha and Jara respectively?
Solution:
Given,
Aysha's investment = Tk. 85,000
Jara's investment = Tk. 15,000
Time = 2 years for both
The ratio of profit earned after 2 years between Aysha and Jara respectively = (85000 × 2) : (15000 × 2)
= 170000 : 30000
= 17 : 3

Question: In a business, the ratio of the capitals of A and B is 2 : 1, that of B and C is 4 : 3 and that of D and C is 6 : 5. What is the ratio of the capitals of A and D?
Solution:
Given,
A : B = 2 : 1 ⇒ A/B = 2/1
B : C = 4 : 3 ⇒ B/C = 4/3
D : C = 6 : 5 ⇒ C/D = 5/6
Now, A/D = (A/B) × (B/C) × (C/D)
= (2/1) × (4/3) × (5/6)
= 20/9
∴ A/D = 20 : 9

Question: A shopkeeper marks his goods 40% above the cost price and offers a discount of 20% on the marked price. What is his gain percent?
Solution:
Let,
the cost price (CP) be Tk. 100
Marked Price = 40% more than cost price
= 100 + 40
= 140 Tk.
Discount = 20% of 140
= (20/100) × 140
= 28 Tk.
Selling Price (SP)= 140 - 28 = 112 Tk.
∴ Profit = SP - CP = 112 - 100 = 12 Tk.
∴ Gain percent = 12%

এখানে,
অর্ধ-বার্ষিক সুদের হার = 12% ÷ 2 = 6%
প্রথম জমা (1লা জানুয়ারী):
আসল, P1 = 5000 টাকা
সময়, n1 = 1 বছর = 2 অর্ধ-বছর
সুদের হার, r = 6%
চক্রবৃদ্ধি মূল (A1) = P1 (1 + r/100)n1
= 5000 × (1 + 6/100)2
= 5000 × (106/100)2
= 5000 × (106/100) × (106/100)
= 5618 টাকা
দ্বিতীয় জমা (1লা জুলাই):
আসল, P2 = 5000 টাকা
সময়, n2 = 6 মাস = 1 অর্ধ-বছর
সুদের হার, r = 6%
চক্রবৃদ্ধি মূল (A2) = P2 (1 + r/100)n2
= 5000 × (1 + 6/100)1
= 5000 × (106/100)
= 5300 টাকা
মোট প্রাপ্ত মূল = A1 + A2 = 5618 + 5300 = 10918 টাকা
মোট জমা = 5000 + 5000 = 10000 টাকা
∴ মোট অর্জিত সুদ = মোট প্রাপ্ত মূল - মোট জমা
= 10918 - 10000 = 918 টাকা
