Solution:
Sachin answered right in First three abilities and all question from easy category. it means his right answered was (6 × 5) + (10 × 3) + (4 × 3)
= 30 + 30 + 12
= 72
Sachin gave wrong answer to the question of 4 and 5 level from medium and difficult category = (10 × 2) + (4 × 2)
= 20 + 8
= 28
Marks scored by Sachin = 72 × 1 - (28 × 0.33)
= 72 - 9.24
= 62.76
Then Sachin expected score is 62.76.
