In the following diagram, circle represents businessman, square represents dancers, triangle represents musicians and rectangle represents Indians.

Who among the following is neither a dancer nor a musician but is a businessman and not an Indian?

In the following diagram, circle represents businessman, square represents dancers, triangle represents musicians and rectangle represents Indians.

We need to find who is neither a dancer nor a musician but is a businessman and not an Indian.

Businessman - yes

Dancer - no

Musician - no

Indian - No

We know  circle represents businessman = (3,5,7,9,10)

Now, we will remove dancers (square) from it - (5,7)

We will also remove musician (triangle) from it - (3,5,7,9)

Therefore, now only 10 is left.

That is the correct answer.
