None of these
Answer: Option B
Solution
Answer: Option B
Solution:
Total days of rainfall = 13.
11 Mornings enjoyed and 12 Afternoons enjoyed, so it means there was rain on 6 mornings and 7 afternoons.
So, extra days without rain are 5 days (11-6 or 12-7).
Total no of day they live,
= No. of days of rain + Days without rain,
Or, 13 + 5 = 18days.
