In this chapter, we will apply our mathematical knowledge to solve various problem.

Some of these problems/ along with their solutions are given below.

•          Example:

What is the time in the clock? (a) 6 : 45                                                           (b) 10 : 10

(c) 1 : 50                                                           (d) All the above

(e) None of these

Ans.     (c)

Explanation: Clearly hour hands is in between 1 and 2, and minute hand is at 10. Hence option (c) is the correct answer.

•          Example:

Which box have maximum number of lighted candles? (a) Box B                                                          (b) Box A

(c) Box C                                                           (d) All the above

(e) None of these

Ans.     (b)

Explanation: Clearly Box A has maximum number of lighted candles.

•          Example:

How many numbers given in the following figure have 4 at the units place? (a) 4                                                                              (b) 2

(c) 6                                                                  (d) All the above

(e) None of these

Ans.     (b)

Explanation: Here only 24 and 64 have 4 at units place.

•          Example:

How many circles are there in the following figures? (a) 15                                                                (b) 20

(c) 17                                                                (d) All the above

(e) None of these

Ans.     (b)

Explanation: Here total number of circles in the figure is = 8 + 6 + 6 = 20
