Solution

The correct option is B $125$
Let the number be $x .$
Given 16% of 40% of $x = 8$
or $\frac{16}{100} \times \frac{40}{100} \times x = 8$
or $x = \frac{8 \times 100 \times 100}{16 \times 40} = 125$

Let the number be $x .$
Given 16% of 40% of $x = 8$
or $\frac{16}{100} \times \frac{40}{100} \times x = 8$
