To find, the height of A = ?

Given by question,

The height of B = 175 cm

∴ 7x = 175

∴ The height of A = 5 × 25 cm

= 125 cm

Thus, the height of A is equal to 125 cm.

Answer 2

Height of A is 125 kg.

Step-by-step explanation:

Ratio of heights of A and B = 5 : 7

To find the height of A:

Let us take 5x and 7x be the heights of A and B.

Height of B = 175

⇒ 7x = 175

$\Rightarrow x=\frac{175}{7}$

⇒ x = 25

Height of A = 5x

                   = 5 × 25

                   = 125

Height of A is 125 kg.
