### Why can't we test our IQ?

10 years ago
I am thinking about a game. It may be any type of puzzle that can bring more participation. When someone find its answer, let another member start with another puzzle or funny question and let it go on. I think it will be interesting.
Let me initiate this thread with this simple mathematical question.

I am giving you a mathematical equation
101 - 102 = 1. We know, the equation is wrong.
You can change the position of any digit or symbol only once. No interchange can be done. And make the equation correct.

Let me see who finds its answer first.

• 101-10 raised to the power of 2 = 1

• 101-10 raised to the power of 2 = 1

Really great!!!!!!!You are a genius. Now you start with a new once.

101 -102 + 1= 0

Absolutely no.
We can change either a digit or a symbol, can't insert anything extra.You inserted a + extra

• I don't think anyone can give a smart reply as chinmoy sir has given.

• Why can't an another member post some interesting question?

Meera sandhu

• The equation should be:

102-101=1 or -101 + 102 = 1

However this may be test of mathematics and not IQ which differs.

Sir,

Read the question again. It was not asked to find a mathematical solution. It was a problem to solve with intelligence.
