Question

11. A's and B's heights are in the ratio 4:5. If B's and C's
heights are in the ratio 3:4, who is the tallest among
the three?​

Answer 1

Answer:

C

Step-by-step explanation:

ratio of A and B =4/5 so clearly B is taller

ratio of B and C =3/4 so clearly C is taller

Answer 2

A:B = 4:5 So, A/B = 4/5

B:C = 3:4 So, B/C = 3/5

To make B equal in both cases,

we have to multiply

• 4/5×3/3 = 12/15
• 3/4×5/5 = 15/20

Now, A:B = 12:15

and B:C = 15:20

From here, we can say that

A' height = 12 unit,

B' height = 15 unit, and

C' height = 20 unit.

So, we can see C's height is more than that of A and B.

Hence, C is the tallest among the three.

Hope this helps you to get to your answer.
