Q.1
Medium
In a series: 5, 11, 23, 47, ?, what is the next number?

Q.2
Medium
If CAT = 3, DOG = 3, ELEPHANT = 4, then ZEBRA = ?
Explanation:
Count of vowels: CAT(A)=1, DOG(O)=1, ELEPHANT(E,A)=2, ZEBRA(E,A)=2. Actually, ZEBRA has E and A = 2 vowels. Wait - checking again: Z-E-B-R-A has E,A = 2. Let me reconsider: if counting syllables or letters with curves: Z(0),E(0),B(1),R(0),A(0)=1? Pattern might be unique letters or vowel positions. ZEBRA = 5 letters.
