DSSSB TGT Natural Science Mock Test - 3 - DSSSB TGT/PGT/PRT MCQ

The correct answer would be Option B. 
The Rowlatt Act aimed at imprisonment without trial and summary procedures for trial. Despite much opposition, the Rowlatt Act was passed in March 1919. The purpose of the act was to curb the growing nationalist upsurge in the country. Mahatma Gandhi, among other Indian leaders, was extremely critical of the Act and argued that not everyone should be punished in response to isolated political crimes.
 

Newton's first law of motion -sometimes referred to as the law of inertia-states that every object will remain at rest or in uniform  motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia.

In December 1977, the Janata Government appointed a committee on Panchayati Raj institutions under the chairmanship of Ashoka Mehta.

Panini was a Sanskrit grammarian from Pushka lavati, Gandhara. He is known for his Sanskrit grammar, particularly for his formulation of the 3,959 rules of Sanskrit morphology, syntax and semantics in the grammar known as Ashtadhyayi (meaning"eight chapters").

• India’s Polar Satellite Launch Vehicle, in its fifty-first flight (PSLV-C49), successfully launched EOS-01 along with nine international customer satellites from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota on November 07, 2020. Hence statements 1 and 3 are not correct.
• It will operate in Low-earth orbit. A low Earth orbit (LEO) is relatively close to Earth's surface. It is normally at an altitude of less than 1000 km but could be as low as 160 km above Earth – which is low compared to other orbits, but still very far above Earth's surface. Hence statement 2 is correct.
• EOS-01 is another Radar Imaging Satellite (RISAT) an earth observation satellite that will work together with RISAT-2B and RISAT-2BR1 launched last year, intended for several applications covering agriculture, water resources, urban planning, rural development, mineral prospecting, environment, forestry, ocean resources and disaster management.

North India's largest floating Solar project was inaugurated in Chandigarh.

BPCL is planning to set up a 1 GW renewable energy plant in Rajasthan.

The 7th Nature and Birds Festival will begin in Uttar Pradesh.

9*0.5+0.5 = 5
5*1+1 = 6
6*1.5+1.5 = 10.5
10.5*2+2 = 23
23*2.5+2.5 = 60

All except Defence are forms of attack.

On rechecking, the same consistent shift of –15 (or +11) applies to each letter:

• Z → K (26 → 11)

• R → C (18 → 3)

• Y → J (25 → 10)

• Q → B (17 → 2)

Applying –15 to P W O V:

• P (16) → 16 – 15 = 1 → A

• W (23) → 23 – 15 = 8 → H

• O (15) → 15 – 15 = 0 → Z

• V (22) → 22 – 15 = 7 → G

So the correct analogue is AHZG

First and fouth letters are interchanged while second and third letters are interchanged.

If D is Male, the answer is Nephew.

If D is Female, the answer is Niece.

As the sex of D is not known, hence, the relation between D and A cannot be determined.

Note: Niece - A daughter of one's brother or sister, or of one's brother-in-law or sister-in-law. Nephew - A son of one's brother or sister, or of one's brother-in-law or sister-in-law.

Therefore, A is sitting in between B and C.

The difference between the exports from the Companies X and Y during the various years are:

In 1993 = Rs. (80 - 30) crores = Rs. 50 crores.

In 1994 = Rs. (60 - 40) crores = Rs. 20 crores.

In 1995 = Rs. (60 - 40) crores = Rs. 20 crores.

In 1996 = Rs. (70 - 60) crores = Rs. 10 crores.

In 1997 = Rs. (100 - 80) crores = Rs. 20 crores.

In 1998 = Rs. (100 - 50) crores = Rs. 50 crores.

In 1999 = Rs. (140 - 120) crores = Rs. 20 crores.

Clearly, the difference is minimum in the year 1996.

8% of 800 for 4 years + 6% of 800 for 4 years = 64 x 4 + 48 x 4 = 256 + 192 = 448. However, we do not know the rate of interest applicable in the 5 th year and hence cannot determine the exact simple interest for 9 years.

Total work = 15 × 210 = 3150 man days.
After 100 days, work done = 15 × 100 = 1500 man days.
Work left = 3150 – 1500 = 1650 man days.
This work has to be done with 30 men working each day.
The number of days (more) required = 1650/30 = 55 days.

52254 – 3512 + 119 = 48861

So Option B is correct

Answer – b) decrease 4.32% Explanation : Let initially seats are 100 and price of each seat is 100, so total initial revenue = 10000
now, seats are 92 and price of each seat = 104, so total revenue = 92*104 = 9568 so percent change in revenue = (432/10000)*100 = 4.32 decrease

Answer – a) 10% Explanation : Let initially income is 100. So, expenditure = 60 and saving = 40 now income is increased by 20% i.e. 120. So, expenditure = (70/100)*120 = 84 and saving = 36 so % percent decrease in saving = (4/40)*100 = 10%

A gets 10% of the profit for managing the business = 10% of 9600 = Rs. 960
Profit remaining = 9600 - 960 = Rs. 8640
Ratio in which they will share the remaining profit = 12 : 20 = 3 : 5
A's share = 960 + (3/8) 8640 = Rs. 4200

Let the numbers be x, y and z.
x + y + z = 98
Also, x : y = 2 : 3 and y : z = 5 : 8
Therefore, x : y : z = 10 : 15 : 24
Let x = 10k, y = 15k and z = 24k
Then, 10k + 15k + 24k = 98 
⇒ k = 2
The numbers are 20, 30 and 48.
Hence, second number is 30.

Lateral surface area (L. S. A.) = 2πrh
Total surface area = (T. S. A.) = 2πr(r + h)

5h = 3h + 3r
2h = 3r

r² = 196
r = 14 m

= 12,936 cubic m
