Answer 1

Answer:

125

Step-by-step explanation:

If the boys are 5/9 of total no. of children, then no. of girls = 1 - 5/9 = 4/9 of total no. of children

Let total no. of children = x

now,

$\frac{4x}{9} = 100 \\ = > x = \frac{100 \times 9}{4} = 225$

Hence, total no. of children = 225

now, no. of boys = 225-100 = 125
