Geometrical Figures In this section, for asking question a Venn diagram is given with certain geometrical figure in it. Each geometrical figure in the diagram represents a certain class. A student is required to study and analyse the figure carefully and then answer certain questions on the basis of given data. ·

Example:
Study the figure given below carefully and answer the questions that follow:

Which number belongs to all the figures?

(a) 3 (b) 4

(e) None of these

Ans. (e)

Explanation: Clearly, we have to find a number which lies inside each one of the four figures - triangle, square,

oval and hexagon. There is no such number in the given diagram. Hence, the answer is (e)

What is the sum of the numbers which belong to two figures only?

(a) 6 (b) 15

(e) None of these

Ans. (c)

Explanation: We first have to find out the numbers which belong to two figures only.

Numbers common to square and oval: 2, 4

Numbers common to triangle and oval: 6

Numbers common to hexagon and oval: 8

The numbers common to square and triangle i.e. 3 or triangle and hexagon i.e., 9 lie inside the oval also, and hence

none of them shall be considered here.

Required sum

What is the product of the number which belong to three figures only?

(a) 27 (b) 162

(e) None of these

Ans. (a)

Explanation: We first find the numbers which belong to three figures only.

Number common to square, triangle and oval: 3

Number common to triangle, hexagon and oval: 9

Required product

What is the sum of the numbers which belong to one figure only?

(a) 5 (b) 16

(e) None of these

Ans. (c)

Explanation: We first find the numbers which belong to one figure only.

Number inside the square only: 1, 3

Numbers inside the oval only: 1, 5, 7

Number inside the hexagon only: 4

Required sum

Hence, the answer is (c)

What is the product of the numbers which belong to two figures only?

(a) 64 (b) 192

(e) None of these

Ans. (c)

Explanation: We first find the numbers which belong to two figures only.

Clearly, such number are 2, 4, 6, 8

Required product

Hence, the answer is (c)

(a) 2 (b) 5

(e) None of these

Ans. (a)

Explanation:

The number common to the triangle, circle and square is 2.

What are the numbers that lie inside any two figures?

(a) 2, 1 (b) 5, 1
