Question

Sex ratio is defined as the number of females per 1000 males in the population. Find the sex ratio, if there are 3732 females per 4000 males in a town.

Answer 1

Number of males $=3732$

Number of females $=4000$

Sex ratio $=\frac{\text{Number of females}}{\text{Number of males}}$

= $\frac{3732}{4000}$ = $\frac{933}{1000}$ [on dividing numerator and denominator by 4]

Hence, the required sex ratio is 933 in the town.
