There were 160 students who participated in the data collection.
The total number of students who like Science and Hindi are :

• A. 45
• B. 32
• C. 16
• D. 48

Answer 1

The correct option is D

48

The total number of students who took part in the survey = 160.
The number of students who like Science = 20% or 0.2
Hence the number of students who like Science = 0.2 $\times$ 160 = 32.
The number of students who like Hindi = 10% or 0.1
Hence, the number of students who like Hindi = 0.1 $\times$ 160 = 16
Hence the total number of student who like Science and Hindi = 32 + 16 = 48
