For correct answer = +5

For incorrect answer = -2

For unattempted answer = 0

•

•

Student gets right = 6

So, marks obtained = 6×5 = 30

Student gets wrong = 4

So, marks Obtained = 4×(-2) = -8

Student leaves unattempted = 10

So, marks obtained = 10×0 =0

Hence, total marks will be

= 30 + (-8) + 0

= 22 answer
