Cei asked 80 people which mode of transport they used to get into town, out of car, bus and bicycle.
24 of the people were male.
11 of these males used a bicycle to get into town.
16 females used the bus to get into town.
17 out of the 28 people who used a car were female.
Work out the number of people who used the bus to get into town.

Total number person using bus = 16 + 2 = 18

Hence, Total number person using bus to get to town is 18  .

Step-by-step explanation:

Given :

Total number of people = 80

Total number of male = 24

Number of male who use bicycle = 11

Number of female who use bus = 16

Number of people use car = 28

Number of female who use car = 17 out of 28

To find :

The number of people use bus to get to town

Solution :

Number of female who use bus = 16          ..........1

Number of female who use car = 17

Number of female use bicycle =

Number of male uses bicycle = 11

As Total number of male = 24

So, rest of male use either bus or car = 24 - 11 = 13

Since

number of people use car = 28

And number of female use car = 17

So, Number of male use car = 28 - 17 = 11

Again

As 11 male using car, so from 13 male using either car or bus

Number of male using bus = 13 - 11 = 2
