Which number is in the square, ellipse and triangle?

The correct answer is Option (1) → 7

A number belongs to a shape when it lies inside the boundary of that shape, so the number asked for must sit in the part shared by all three. The figure has two four-sided shapes: the larger one, with 4 at its top, is the square; the long flat one, with 1 in it, is the rectangle.

• 7 — inside the square, the ellipse and the triangle

• 6 — inside the square and the ellipse, but not the triangle

• 5 — inside the square, the rectangle and the ellipse, but not the triangle

• 1 — inside the rectangle only
