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 for HPCL Mechanical Engineer Mock Test - 1 - Question 4

Length of the rectangle = 5x
Breadth of the rectangle = 4x
5x × 4x = 320
x2 = 16
x = 4

Which of the following  (100 - 990) x 100?
Detailed Solution for HPCL Mechanical Engineer Mock Test - 1 - Question 7


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.

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 for HPCL Mechanical Engineer Mock Test - 1 - Question 13

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 for HPCL Mechanical Engineer Mock Test - 1 - Question 14

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 for HPCL Mechanical Engineer Mock Test - 1 - Question 22
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.
