The ratio of the length to the breadth of a rectangle is 5 : 4 and the area of the rectangle is 320 cm2, what is the perimeter of the rectangle?

Detailed Solution: Question 4

Length of the rectangle = 5x
Breadth of the rectangle = 4x
5x × 4x = 320
x2 = 16
x = 4
So the answer = 2 × (5x + 4x) = 2 × 9x = 2 × 9 × 4 = 72 cm
Hence, Option B is correct.

In a year, the average monthly expenditure of Rajat in the first 5 months is Rs. 21,000, in the next 4 months is Rs. 24,000 and in the last three months is Rs. 12,000. If he saves overall Rs. 1,80,000 in the whole year, what is his average monthly income?

Detailed Solution: Question 6

Total income of the year = 5 × 21,000 + 4 × 24,000 + 3 × 12,000 + 1,80,000 = 4,17,000

Hence, Option B is correct.

HPCL Mechanical Engineer Mock Test - 1 - Question 7
Save

A person crosses a 600 m long street in 5 minutes. What is his speed in km per hour?

Detailed Solution: Question 7

It is given in the question that a man crosses 600m long street in 5 minutes. We have to find the speed of the man in km per hour. To find the speed of the man in km per hour, we have to convert the given distance to km and also convert the given time to hour.
First, let us see the conversion of the given distance into km. We know that 1km = 1000m.
So, to convert 600m to km, we can write, 600m = x km.
x = 600/1000 km 
x = 0.6km 
Now, let us convert the given time into hours. We know that 1 hour = 60 minutes.
So, to convert 5 minutes to hours, we can write, 5 minutes = y hours.
y = 5/60 hrs
y = 0.083 hrs
Now we know that speed can be found out using the formula, Speed=Distance/Time, We have found out that distance = 0.6km and time = 0.083 hrs. So, on substituting these values in the formula of speed, we get,  
Speed = 0.6/ 0.083
= 6×1000 / 83 × 10
= 6000/ 830
= 600/83
= 7.2 km/h
Therefore, we get the speed of the man crossing a 600m long street in 5 minutes as 7.2km/h.
Hence, option (D) is the correct answer.

HPCL Mechanical Engineer Mock Test - 1 - Question 8
Save

Which of the following  (100 - 990) x 100?

Detailed Solution: Question 8


To solve this problem, we need to evaluate the expression (100 - 990) x 100. Let's break it down step by step:
Step 1: Evaluate 990: Any number raised to the power of 0 is equal to 1. So, 990 = 1.
Step 2: Substitute the value of 990 into the expression: (100 - 1) x 100 = 99 x 100.
Step 3: Multiply 99 and 100: 99 x 100 = 9900.
Therefore, the value of the expression (100 - 990) x 100 is 9900.
Hence, the correct answer is C: 9900.

  • A : B : C = 150 : 75 : 100 = 6 : 3 : 4
  • A : B : C = 6 : 3 : 4
  • Hence, Option D is correct.

Decimal representation of a rational number cannot be 

Detailed Solution: Question 11

A rational number is a number that can be expressed as a fraction p/q, where p and q are integers and q ≠ 0 

  • Its decimal representation is either terminating (like 0.75 = ¾)
    or non-terminating but repeating (like 0.333... = ⅓).

  • It cannot be non-terminating and non-repeating, because that form represents an irrational number (like π or √2).

 Therefore, the decimal representation of a rational number cannot be non-terminating and non-repeating.

To qualify for Physical in Sub-inspector and Army recruitment, the minimum age required is 19 years and 18 years respectively, the minimum weight required is 50 kgs and 48 kgs respectively, and maximum height allowed is 170 cms and 163 cms respectively. Karan is 17 years old, has a weight of 47 kgs, and has a height of 161 cms. For which of this recruitment is he eligible?  

Detailed Solution: Question 15

The logic follows here is:

Now,

Karan is 17 years old, has a weight of 47 kgs, and a height of 161 cms.

It is clearly mentioned in the criteria of Physical in Sub-inspector and Army recruitment about the weight and height of the candidate. Karan has a weight of 47 kgs and a height of 161 cms which is less than the criteria set for both the recruitment. Therefore, Karan neither qualifies for Physical in Sub-inspector and Army recruitment.

Hence, the correct answer is "Neither Sub-inspector nor Army recruitment".

Six persons – Veer, Prakash, Bhola, Shiv, Ankur and Bhanu were sitting around a circular table facing towards the centre. Who was sitting to the immediate right of Bhanu?

Statement I: Ankur was sitting second to the right of Veer, who was sitting to the immediate left of Bhola. Prakash was sitting second to the left of Bhola.
Statement II: Shiv was sitting to the immediate right of Ankur, who was sitting second to the right of Veer. Prakash was sitting second to the left of Bhola, who is to the immediate left of Ankur.

Detailed Solution: Question 16

Checking Statement I:
Using the above references, we get the following arrangement:

Since there is no information about the position of Bhanu so we cannot find the person who sits on the immediate right of Bhanu.

Hence, data in statement I alone is not sufficient.
Checking Statement II:
Using the above references, we get the following arrangement:

Clearly, Prakash sits on the immediate right of Bhanu.

Hence, data in statement II alone is sufficient.

Hence, Option B is correct.

A long fin extends from the external surface of a cylinder through which hot fluid flows; the excess temperature at the tip of the fin would be

Detailed Solution: Question 25

Determination of fin length is an important step in designing a fin once its cross-sectional area has been determined. The longer the fin, the larger is the surface area, and the higher is the heat transfer. However, it is not necessary that the fin should be infinitely long for maximum heat transfer. It has been observed that the temperature drops along the fin exponentially and reaches an environmental temperature at some point along the fin length. Beyond this point, the length of the fin does not contribute to the heat transfer; therefore, designing extra-long fin results in material waste, excessive weight, and increased size at increased cost without any benefit in return.
