Nora’ dog is 7 months older than Qity’s dog. Qity’s dog is 9 months younger than Sandy’s dog. Sandy’s dog is 5 months older than Wale’s dog. Wale’s dog is 10 months younger than Leslie’s dog. Whose dog is the youngest? Correct Answer Qity

According to the given information:

1) Nora’ dog is 7 months older than Qity’s dog. → N > Q.
Therefore, Nora’ dog = Qity’s dog + 7

2) Qity’s dog is 9 months younger than Sandy’s dog → Q < S.
Therefore, Sandy’s dog = Qity’s dog + 9

From 1 and 2, Nora’ dog < Sandy’s dog
Therefore, Sandy’s dog – Nora’ dog = 2

3) Sandy’s dog is 5 months older than Wale’s dog → S > W.
Therefore, Sandy’s dog = Wale’s dog + 5

4) Wale’s dog is 10 months younger than Leslie’s dog → L > W
Therefore, Leslie’s dog = Wale’s dog + 10

Thus, Leslie’s dog > Sandy’s dog > Wale’s dog, Nora’ dog > Qity’s dog
Hence, Qity’s dog is the youngest dog among all others.
