Question

250 students in a group were asked whether they like mango or apple. 80 students like but not apple and 60 students like apple but not mango. If 50 students do not like both of the fruits, then Represent the above information in Venn-diagram. Find the ratio of the students who like mango to the students who like apple. ​

Answer 1

Ratio of the students who like mango to who like apple = 7:6

Explanation:

Given:

Total number of students = 250

Number of student like only mangoes = 80

Number of student like only apple = 60

Both dont like = 50

Find:

Ratio of the students who like mango to who like apple

Computation:

Number of student who like both = 250 - 80 - 60 - 50

Number of student who like both = 60

Ratio of the students who like mango to who like apple = [80+60] / [60 + 60]

Ratio of the students who like mango to who like apple = 140 / 120

Ratio of the students who like mango to who like apple = 7:6
