Question

On an annual basis, a hospital delivers 1820 babies. If 55% of the babies born are male, how many females are born in a year?

Answer 1

The total number of babies is 1820

If 55% of the babies born are male, then the percentage that the babies born are female is,

$100-55=45$

Therefore, the percentage of female babies is 45%. Let n be the number of female babies born in a year. Therefore, we have,

$n=\frac{45}{100}\times1820=819$
