প্রশ্ন: যদি P = 16 এবং TAP = 37 হয় তবে CUP-কত?
সমাধান:
দেওয়া আছে,
P = 16
এবং TAP = 37
ইংরেজি বর্ণমালা হতে পাই,
T + A + P = 20 + 1 + 16 = 37
সেই অনুসারে,
CUP = C + U + P = 3 + 21 + 16 = 40
অর্থাৎ, CUP এর মান 40.

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?
Created: 12 hours ago
A
5 : 9
B
12 : 17
C
11 : 15
D
20 : 9
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

The ratio of milk and water in a solution is 7 : 4. After adding 8 liters of water, the ratio of milk and water becomes 3 : 2. Find the final amount of water in the solution.
Created: 11 hours ago
A
48 liters
B
54 liters
C
56 liters
D
60 liters
Solution:
Let the initial amount of milk = 7x liters
Let the initial amount of water = 4x liters
According to the question,
7x/(4x + 8) = 3/2
⇒ 2 × 7x = 3 × (4x + 8)
⇒ 14x = 12x + 24
⇒ 14x - 12x = 24
⇒ 2x = 24
⇒ x = 12
∴ Final amount of water = 4x + 8
= 4 × 12 + 8
= 48 + 8 = 56 liters
