# Aptitude Problems on Ages

Aptitude is a very important aspect of a person’s life. By aptitude, we usually understand Quantitative aptitude that basically judges our analytical and problem-solving skills. Aptitude is one of the most important parts of competitive exams and job interviews. You will find Aptitude questions in almost every exam paper. The reason is to judge the problem solving and decision-making skills of the candidate

# Time and Distance

1. Speed, Time and Distance:
 Speed = Distance , Time = Distance , Distance = (Speed x Time). Time Speed
2. km/hr to m/sec conversion:
 x km/hr = x x 5 m/sec. 18
3. m/sec to km/hr conversion:
 x m/sec = x x 18 km/hr. 5
4. If the ratio of the speeds of A and B is a : b, then the ratio of the
 the times taken by then to cover the same distance is 1 : 1 or b : a. a b
5. Suppose a man covers a certain distance at x km/hr and an equal distance at y km/hr. Then,
 the average speed during the whole journey is 2xy km/hr. x + y
Examples

1.
A person crosses a 600 m long street in 5 minutes. What is his speed in km per hour?
 A. 3.6 B. 7.2 C. 8.4 D. 10
Explanation:
 Speed = 600 m/sec. 5 x 60
= 2 m/sec.

 = 2 x 18 km/hr 5
= 7.2 km/hr.

# Logical Reasoning

1
Look at this series: 2, 1, (1/2), (1/4), ... What number should come next?
 A. (1/3) B. (1/8) C. (2/8) D. (1/16)
Explanation:
This is a simple division series; each number is one-half of the previous number.
In other terms to say, the number is divided by 2 successively to get the next result.
```4/2 = 2
2/2 = 1
1/2 = 1/2
(1/2)/2 = 1/4
(1/4)/2 = 1/8 and so on.```

```
2.
Look at this series: 7, 10, 8, 11, 9, 12, ... What number should come next?

A.7
B.10
C.12
D.13

Explanation:

This is a simple alternating addition and subtraction series. In the first pattern, 3 is added; in the second, 2 is subtracted.

3.
Look at this series: 36, 34, 30, 28, 24, ... What number should come next?

A.20
B.22
C.23
D.26

Explanation:

This is an alternating number subtraction series. First, 2 is subtracted, then 4, then 2, and so on.

4. Look at this series: 22, 21, 23, 22, 24, 23, ... What number should come next?

A.22
B.24
C.25
D.26

Explanation:

In this simple alternating subtraction and addition series; 1 is subtracted, then 2 is added, and so on.

5.
Look at this series: 53, 53, 40, 40, 27, 27, ... What number should come next?

A.12
B.14
C.27
D.53

Explanation:

In this series, each number is repeated, then 13 is subtracted to arrive at the next number.
