Question : The given pie chart shows the percentage of students who speak different languages in a hostel. The total number of students in the hostel is 120.
What is the ratio of students who speak English and Bhojpuri to those who speak Tamil?
Option 1: 10 : 3
Option 2: 1 : 1
Option 3: 20 : 3
Option 4: 5 : 1
Correct Answer: 5 : 1
Solution :
Total number of students in the hostel is 120.
Students who speak English = 120 × $\frac{15}{100}$ = 18
Students who speak Bhojpuri = 120 × $\frac{10}{100}$ = 12
Students who speak Tamil = 120 × $\frac{5}{100}$ = 6
$\therefore$ Required ratio = (18 + 12) : 6 = 30 : 6 = 5 : 1
Hence, the correct answer is 5 : 1.
