Father to his son- How was the paper?

Son- bas pehla sawal chut gaya.

Father- acha,aur baki?

Son- 3rd mujhe ata nahi tha,

4th main karna bhul gya,

5th mujhe nazar nahi aya nd 6th paper ki pichli taraf tha meine dekha nahi.

Father gusse me bola- aur 2nd ques?

Son- bas sirf wahi galat hua hai!
