उत्तर
∵ 60 + 45 + 42 + 48 + 75 = 270
∴ Central angle for Hindi = `60/270 xx 360^circ = 80^circ`
Central angle for English = `45/270 xx 360^circ = 60^circ`
Central angle for Maths = `42/270 xx 360^circ = 56^circ`
Central angle for Science = `48/270 xx 360^circ = 64^circ`
and Central angle for Social study =`75/270 xx 360^circ = 100^circ`
