Question

Eric found that about 62% of 80 classmates at school like hip-hop music. However, 70%of his 60 relatives like hip-hop. Do more classmates like hip-hop or relatives?

Answer 1

relatives have more than classmates

Answer 2

Classmates like more hip hop then Relatives

Explanation:

Given:

62 % of 80 class mates likes hip hop

and

70% of 60 relatives like hip hop music

To find :

who likes more hip hop

Solution:

We have to find the no of class mates and family relatives who like hip hop and we will get to know that who like more hip hop class mates or family members

so

Class mates who like hip hop are = 62 % of 80

= 62 % * 80

as 62 % =
`(62)/(100)`

so it becomes

Class mates who like hip hop are =
`(62*80)/(100)`

Solving it gives

Class mates who like hip hop are =
`(4960)/(100)`

=49.6

which is approximately 50 classmates like hip hop

Relatives who like hip hop are = 70 % of 60

= 62 % * 80

as 70 % =
`(70)/(100)`

so it becomes

Relative who like hip hop are =
`(70*60)/(100)`

Solving it gives

Relatives who like hip hop are =
`(4200)/(100)`

=42

which is approximately 42 relatives like hip hop

So as we can see from the results more no of class mates like hip hop then relatives
