The sum of the four numbers A, B, C and D is 875. If the ratio of A to B is 1:2, the ratio of B to C is 3:1 and the ratio of C to D is 2:3, find the value of C.
- A120
- B130
- C125
- D135
Solution & Step-by-step Explanation
We are given the following individual ratios:
A:B=1:2
B:C=3:1
C:D=2:3
First, let's combine the ratios for A, B, and C:
To equate B in both ratios, multiply A:B by 3 and B:C by 2:
A:B=3:6
B:C=6:2
So, A:B:C=3:6:2
Now, combine with C:D=2:3. Since the value of C is already 2 in both parts, we can directly merge them:
A:B:C:D=3:6:2:3
Let the numbers be 3x, 6x, 2x, and 3x. Their sum is:
3x+6x+2x+3x=875
14x=875
x=
14
875
=62.5
The value of C is 2x:
C=2×62.5=125
A:B=1:2
B:C=3:1
C:D=2:3
First, let's combine the ratios for A, B, and C:
To equate B in both ratios, multiply A:B by 3 and B:C by 2:
A:B=3:6
B:C=6:2
So, A:B:C=3:6:2
Now, combine with C:D=2:3. Since the value of C is already 2 in both parts, we can directly merge them:
A:B:C:D=3:6:2:3
Let the numbers be 3x, 6x, 2x, and 3x. Their sum is:
3x+6x+2x+3x=875
14x=875
x=
14
875
=62.5
The value of C is 2x:
C=2×62.5=125
