Question

Arjun's height was 150 cm last year. This year he is 5% taller. What is Arjun's height now

Answer 1

Last year Arjun's height=150cm
Percentage of increase in height this year=5%
Total increase in height =5%x150cm.
=5/100x150cm
=15/2cm=7.5cm.
Therefore, present height=(150+7.5)cm
=157.5cm.
So, present height of Arjun=157.5cm.
