Total questions =10
Both part correct earns 5 points
One part correct earns 2 ponts
No parts correct earns - 1 points
P I-squared
Both = 4
One = 2
None = 4
Total points = (5×4) + (2×2) + (-1×4)
= 20 + 4 - 4
= 20
Point per question = 20/10 = 2
Euler circles
Both = 2
One = 6
None = 2
Total points = (5×2) + (2×6) + (-1×2)
= 10 + 12 - 2
= 20
Point per question = 20/10 = 2
Both team got equal points...
Hope this will help....
