Mr.Intelligent

A Sardar is invited to tea with President Abdul Kalam.
He asks President Kalam what his leadership philosophy is.
He says that, it is to surround himself with intelligent people.sardar asks how he knows if they're intelligent.
"I do so by asking them the right questions," says President Kalam.
"Allow me to demonstrate. Sardar watches as President Kalam phones Manmohan Singh, the Indian Prime Minister and says,
"Mr. Prime Minister, please answer this question: your mother has a child, and your father has a child, and this child is not your brother or sister.
Who is it?"
Manmohan immediately responds,
"It's me, Sir !"
"Correct. Thank you and good-bye, sir," says Kalam.
He hangs up and says,
"Did you get that, Mr. Sardar?"
Sardar nods:
"Yes Mr. President.
Thanks a lot. I'll definitely be using that. Sardar upon returning to his house , decides he'd better put his brother to the test.
Sardar says,
"brother, I wonder if you can answer a question for me."
"Why, of course, Bayya. What's on your mind?"
Sardar poses the question:
"Uhh, your mother has a child, and your father has a child, and this child is not your brother or your sister.
Who is it?" ;The brother was puzzled and finally asks,
"Can I think about it and get back to you?"
Sardar agrees, and his brother leaves.
Sardar's brother immediately calls his other brothers,and they puzzle over the question for several hours, but nobody can come up with an answer.
Finally, in desperation, sardar's brother calls his aunt simran and explains the problem.
"Aunt simran, your mother has a child, and your father has a child, and this child is not your brother or your sister. Who is it?"
Simran answers immediately,
"It's me, of course."
Much relieved, brother rushes back to the elder sardars house, and exclaims,
"I know the answer, Bayya!
I know, who it is!
It's simran!"
And sardar replies in disgust,
"Wrong, its Manmohan Singh!"
