A, B and C are three numbers. If A exceeds B by 70% and B is 20% less than C, then A : C is:
- A32:23
- B33:24
- C35:26
- D34:25
Solution & Step-by-step Explanation
Let the number C be 100.
B is 20% less than C:
B=100−20=80
A exceeds B by 70%:
A=B×(1+
100
70
)=80×1.7=136
Now, find the ratio A:C:
A:C=136:100
Dividing both terms by 4:
A:C=34:25
B is 20% less than C:
B=100−20=80
A exceeds B by 70%:
A=B×(1+
100
70
)=80×1.7=136
Now, find the ratio A:C:
A:C=136:100
Dividing both terms by 4:
A:C=34:25
