The marks of A and B are in the ratios 4:5 and those of B and C are in the ratio 3:2. Find the ratio of marks obtained by A and C?
Answers
The ratio of marks obtained by A and c is 6:5.
Given,
A:B = 4:5.
B:C = 3:2.
To Find,
The ratio of marks obtained by A and C.
Solution,
Using the properties of proportion we will solve the above question,
A:B = 4:5.
B:C = 3:2.
So, the ratio of A, B, and C is
= 4 : 5
3 : 2
Multiply 5 to right empty space and 3 to left space,
= A : B : C
4 : 5 : 5
3 : 3 : 2
Now ,
= A : B : C
12 : 15 : 10
So,
A:C = 12: 10 or 6:5 .
The ratio of marks obtained by A and c is 6:5.

Answer:
The answer to the given question is the ratio of marks obtained by A and C is 6:5
Step-by-step explanation:
Given :
The marks of A and B are in the ratios 4:5
The marks of B and C are in the ratio of 3:2
To find :
The ratio of marks obtained by A and C.
Solution :
This problem can be solved by the properties of proportion.
A:B = 4:5
B:C = 3:2.
The combined ratio of A:B:C is
A:B:C
4:5
3:2
There are few empty spaces to make them occupied multiply 5 by the right space and 3 by the left space.
A:B:C
4:5:5
3:3:2
Now, the value will be changed into a
12:15:10
The above-obtained ratio is the equivalent ratio of A, B and C.
Therefore, the ratio of A:C will be 12:10 or 6:5
Hence, the ratio of marks obtained by A and C is 6:5.
