option a is the answer

Answer 2

Answer:

d. 69

Step-by-step explanation:

Avg of 20 students= 68

Marks of

Sunil=66, Gita=52

=> (marks of 18 students + Sunil's + Gita's) / 20 = 68

marks of 18 students + 66+52 = 68* 20

marks of 18 students + 118 = 1360

marks of 18 students =1360- 118 =1242

Average marks of 18 students = 1242 /18

= 69 Answer
