Step-by-step explanation:

Reshma = 15

Heena = 0

Answer 2

Answer:

i) 8

ii) 15

iii) 0

Step by step Explanation

I) We know that for every correct answer student get +5 but for Incorrect answer -2

so mohan gives four correct and six incorrect

so , 4 × 5 + 6 × -2 = 20 + ( -12)

= 8

ii) We know that for every correct answer student get +5 but for Incorrect answer -2

so Reshma gives five correct and five incorrect

so, 5 × 5 + 5 × (-2) = 25 + ( - 10)

= 15

iii) We know that for every correct answer student get +5 but for Incorrect answer -2 and for no attempt their no marks or 0

so Heena gives two correct and five incorrect and three questions were not attempt by her

so, 3× 0 + 5 × 2 + (-2) × 5 = 10 + (-10)

= 0
