Answer 1

The correct answer to the following question will be Option A (67.9%).

Explanation:

As we know,

The number of total employees will be:

= 480

The number of employees having normal or low BP will be:

= 96 + 230

= 326

Hence, the percentage of low or normal BP workers will be:

=
`((326)/(480) )* 100 \ percent`

=
`67.9 \ percent`

Note:- % (percent)
