Directions: A sentence is given here with a blank and you need to fill the blank choosing the word/words given below. If all the words given can fill the blank appropriately, choose ‘All are correct’ as your answer.

The ship is uncrewed on this occasion, but if it completes the current flight without incident, astronauts will be on the next _______________ in two years' time.

I. Cruise

II. Expedition

III. Outing

Detailed Solution for MPPGCL JE Electrical Mock Test - 8 - Question 1

Let us first learn the meanings of the given words:

Cruise (noun): a voyage on a ship or boat taken for pleasure or as a holiday and usually calling in at several places.

Expedition (noun): a journey undertaken by a group of people with a particular purpose, especially that of exploration, research, or war.

Outing (noun): a short journey made by a group of people, usually for pleasure or education.

The idea here is to express the next trip of the astronauts, as the context is about ‘astronauts’, thus ‘expedition’ is the correct answer while ‘cruise’ and ‘outing’ are contextually weak.

Hence, the correct answer is option A.

In a group of students, each one knows either Hindi or English. If 100 know Hindi, 50 know English and 30 know both, how many students are there in group?
Detailed Solution for MPPGCL JE Electrical Mock Test - 8 - Question 4

The logic followed is:

Therefore, the number of students in the group are 20 + 30 + 70 = 120

The number of students = 120

Hence, the correct answer is "120".

Directions: Each of the following consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question.

In which month of the year is Kirti’s birthday?
Statement I: Kirti correctly remembers that her birthday is in the second half of the year.
Statement II: Kirti’s father correctly remembers that her birthday is after 31st October but before 1st December.
Detailed Solution for MPPGCL JE Electrical Mock Test - 8 - Question 6

Checking Statement I:

Here, as Kirti correctly remembers that her birthday is in the second half of the year, so her birthday is in July or August or September or October or November or December.

Hence data in statement I is not sufficient to answer the question.

Checking Statement II:

Here, as Kirti’s father correctly remembers that her birthday is after 31st October but before 1st December, so we can say that Kirti’s birthday is in November.

Hence data in statement II is sufficient to answer the question.

Hence, Option B is correct.

A power system having 100 buses in which 20 are voltage controlled buses and 10 are generator buses. For the load flow study find the size of jacobian matrix –
Detailed Solution for MPPGCL JE Electrical Mock Test - 8 - Question 13

size of jacobian matrix
= (2n – m – 2)× (2n – m – 2)
n = total number of buses.
m = voltage controlled buses + generator buses
generator bus
= 10-1=9 (∵ one slack bus)
m= 20 + 9 = 29
size of jacobian matrix = (2 x 100 - 29 - 2) x (2 x 100 - 29 - 2) x (2 x 100 - 29 - 2) = 169 x 169
