Hello,
Can you please tell me if my solution is correct:
What fraction of the people who attended a conference had an income of more than
$40,000 a year?
(1) 20% of the people at the conference had an income which was more than or equal to
$40,000 a year.
(2) 5% of the people at the conference had an income of $40,000 a year.
OA: C
I was trying to solve this as follows:
Since the question is asking for a faction, let the total number of people at the conference be 100.
So we need to find the number of people who have an income of more than $40,000
1) 20 people have an income greater than or equal to 40K - in-suff.
2) 5 people have an income of 40K - in-suff.
1 and 2: 15 people have an income greater than 40K.
I was wondering if this solution is correct?
Thanks,
Sri
