Question

Chandana is twice as tall as Raksha. If Raksha is 60 cm shorter than Chandana, how tall is Chandana?

Answer 1

Chandana is twice as tall as Raksha.
So, Chandana's height = 2 $\times$ Raksha's height
Difference between Chandana's and Raksha's height = 2 $\times$ Raksha's height - Raksha's height
= Raksha's height.
We are given that the difference between Chandana's and Raksha's height is 60 cm.
So, Raksha's height = 60 cm
$\therefore$ Chandana's height = 2 $\times$ 60
= 120 cm.
