Solution
The total number of students, N = 500.
For mathematics, θ = 126
No. of students showing
inclination toward Maths = `θ/360xxN=126/360xx500=175`
Similarly,
No. of students showing
inclination towards Social science=`54/360xx500=75`
No. of students showing
inclination towards Science = `72/360xx500=100`
No. of students showing
inclination towards languages = `108/360xx500=150`
Now, `150-100=50`
∴ 50 more students show inclination towards languages than towards science
