Solution
The correct option is D Cannot be determined
l + m – n + o – p * q can be read as l is the sister of m, m is the brother of n, n is the sister of o, os is the brother of p and p is the daughter of q. Thus, l, n and p are females, m and o are males and we do not know the gender of q. Hence, we cannot be sure about the number of females in the string.
