Question
If and , then what is the value of ?
Ops:
A. 35
B. 40
C. 30
D. 45
Solution
The given ratio is a : b = 3 : 5.
This means that 'a' is 3 parts of a whole and 'b' is 5 parts of the same whole.
We are also given that a = 24.
So, 3 parts = 24.
To find the value of 1 part, we divide 24 by 3.
24 ÷ 3 = 8.
So, 1 part = 8.
Since 'b' is 5 parts, to find the value of 'b', we multiply 5 by the value of 1 part.
5 * 8 = 40.
So, the value of 'b' is 40.
Therefore, the correct answer is B. 40.
