Answer: Option C
Explanation:
Since 8th to the left of 12th from the right
is 20th from the right, so from I, we know that Vishakha is 5th from left and
20th from right i.e. there are 4 children to the left and 19 to the right of
Vishakha. So, there are (4 + 1 + 19) i.e. 24 children in the row.
From II, Nisha is 7th from right and 18th
from left end of the row.
So, there are (6 + 1 + 17) = 24 children in
the row.
