(a) The scale : 1 unit = 10 children.

(b) (i) Class fifth has the maximum number of children. 

Whereas, class tenth has the minimum number of children

(ii) Number of students in class sixth = 120

Number of students in class eight = 100

Therefore, the required ratio = \frac{120}{100}

= \frac{6}{5}

Required ratio is 6:5
