Solution

Share

Total angle made by maths and chemistry in pie chart is 160.
Hence their total share will be $$\frac{810}{360} \times 160 $$ = 360
And total share of physics and social science will be 140.
Hence their total share will be $$\frac{810}{360} \times 140$$ = 315
Difference is 360-315=45
