The table below shows the data on likely heights of boys and girls as they grow in age. Draw graphs showing height and age for both boys and girls on the same graph paper. What conclusions can be drawn from these graphs?    

Answer:

At birth, both girls and boys are of the same height. In further years, girls become shorter than the boys. As soon as both girls and boys reach the age of 12 years (puberty age of girls), girls become taller than the boys till the age of 15 years. At 16 years of age, both become of the same height. At the age of 20 years, again girls become shorter than the boys.
