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