DSSSB TGT Social Science Mock Test - 4 - Question 1

Which of the following utility approach is based on the theory of Alfred Marshall?

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 1

The Cardinal Utility approach is propounded by neo-classical economists, who believe that utility is measurable, and the customer can express his satisfaction in cardinal or quantitative numbers, such as 1,2,3, and so on.  Here, one Util is equivalent to one rupee and the utility of money remains constant.

DSSSB TGT Social Science Mock Test - 4 - Question 3

Statements:
Some ants are parrots.
All the parrots are apples.

Conclusions:
1. All the apples are parrots.
2. Some ants are apples.

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 3

From the above Venn diagram we made some assumptions on conclusion:

  • All apples are parrots: False.
  • Some ants are apples: True.

Therefore only the second conclusion is True.

Hence the correct answer is option B.

DSSSB TGT Social Science Mock Test - 4 - Question 4

If in a code language PAINT is written as 74128 and EXCEL as 93596, then how ACCEPT will be written in that language?

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 4

PAINT - 74128
EXCEL - 93596
Since each letter is assigned a unique code in the given words.
Therefore, the code for ACCEPT is 455978.

DSSSB TGT Social Science Mock Test - 4 - Question 5

Directions : In each question below are given two Statements: followed by two conclusion numbered I and II. You have to take the two given statement to be true even if they seem to be at variance with commonly known facts and then decide which of the given Conclusions: logically follows from the two given statement, disregarding commonly know facts.

Statements:                      

             All radios are electric goods.

             All table lamps are electric goods.

Conclusions:       

             I. Some radios are table-lamps.

             II. Some tables-lamps are radios.

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 5

C is the correct option. Neither of the conclusions follows because If all radios are electric goods and all table lamps are electric goods there is a possibility that radios might overlap table lamps but here the conclusions are SOME radios are table lamps and SOME table lamps are radios which we can not say clearly.

DSSSB TGT Social Science Mock Test - 4 - Question 13

A sum of Rs. 14,000 amounts to Rs. 22,400 in 12 years at the rate of simple interest. What is the rate of interest?

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 13

Amount = 22400, P = 14000, T = 12yrs
SI = 22400 - 14000
= 8400
Rate = (8400*100)/(12*14000)
= 5%
 

DSSSB TGT Social Science Mock Test - 4 - Question 14

The price of raw materials has gone up by 15%, labour cost has also increased from 25% of the cost of raw material to 30% of the cost of raw material. By how much percentage should there be a reduction in the usage of raw materials so as to keep the cost the same?

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 14

 Let the initial price of raw materials be 100.
 The new cost of the same raw material would be 115.
 The initial cost of labour would be 25 and the new cost would be 30% of 115 = 34.5

 The total cost initially would be 125.
 The total cost for the same usage of raw material would now be: 115 + 34.5 = 149.5

 This cost has to be reduced to 125. The percentage reduction will be given by 24.5 / 149.5 = 16 % approx. 

DSSSB TGT Social Science Mock Test - 4 - Question 15

Simple interest on a certain sum of money for 4 years at 5% per annum is half the compound interest on Rs. 3000 for 2 years at 10% per annum. The sum placed on simple interest is: 

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 15

C.I = P[(1 + r/100)n - 1]
C.I = 3000[(1 + 0.10)2 - 1]
= 3000(1.21 - 1)
⇒ 3000 * 0.21 
⇒ 630
S.I = 630/2
⇒ 315
As we know that, P = (SI * 100)/(R * T)
⇒ (315 * 100)/(4 * 5)
⇒ 1575

Marked price=60rs.
discount=10%
profit=20%
then,
SP=90%of 60=54
CP=(100/100+20)×SP
=(100/120)×54
=45rs.

DSSSB TGT Social Science Mock Test - 4 - Question 20

 Study the following graph carefully to answer the given questions

Time taken by the pipes to fill a tank/cistern (hours/minutes)

Two pipes, A and B are opened simultaneously and it is found that due to the leakage in the bottom, 17/7 minutes are taken extra to fill the tank. If the tank is full, in what approximate time would the leak empty it?

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 20

Total time taken by both pipes before the leak was developed = 60/7 minutes
now, leaks is developed which will take T time to empty the tank so, (1/15 +1/20 – 1/T) = 1/11
solve for T, we will get 660/17 minutes = 39 minutes (approx.)

DSSSB TGT Social Science Mock Test - 4 - Question 21

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 21

Downstream Speed = 6kmph
Upstream Speed = 8kmph – 6kmph = 2kmph
Speed of Current = (6-2)/2 = 2kmph

Total number of appeared candidates in the years 2014 and 2015 together = 620
Total number of passed candidates in the years 2014 and 2015 together = 520
= 620 : 500
= 31 : 25

DSSSB TGT Social Science Mock Test - 4 - Question 23

When a shopkeeper reduces the selling price of an article from 1180 to 1126 his loss increases by 5% . What is the cost price of article?

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 23

CP = 54 * 100 / 5 = 1080

DSSSB TGT Social Science Mock Test - 4 - Question 24

17 × 756 ÷ √2916 = ? +540

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 24

17*756÷54 = ? +540
17*14 = ? +540
238 = ? + 540
? =238-540 = -302

So option C is correct

DSSSB TGT Social Science Mock Test - 4 - Question 26

A truck travelled to a place Q from P, the first 50 km at 10 kmph faster than the usual speed, but it returned the same distance at 10 kmph slower than usual speed. If the total time taken by the truck is 12 hours, then how many hours will travel at the faster speed?

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 26

Total time taken,
[50/(x-10)] + 50/(x +10)] = 12 hours.
By solving the equation, we get
x = 15
Time is taken by the truck at faster speed = 50/(15+10) = 2 hours.

DSSSB TGT Social Science Mock Test - 4 - Question 27

A piece of work has to be completed in 50 days, a number of men are employed but it is found that only half of the work is done in 30 days, then an additional 20 men were joined to complete the work on time. How many men initially put to work?

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 27

suppose Initially X men get employed. Half work is done in 30 days it means full work will be done by X men in 60 days. Now,
Work done = 1/2 = [20*(x + 20)]/60X
X = 40

DSSSB TGT Social Science Mock Test - 4 - Question 28

The least number, which when divided by 12, 15, 20 and 54 leaves in each case a remainder of 8 is:

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 28

Required number = (L.C.M. of 12, 15, 20, 54) + 8

= 548.

DSSSB TGT Social Science Mock Test - 4 - Question 29

 Ravi got 70% in English and 56% in Biology and the maximum marks of both papers is 100. What percent does he score in Maths, if he scores 60% marks in all the three subjects?. Maximum Marks of Maths paper is 200.

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 29

70 + 56 + x = 60% of all three subjects

70 + 56 + x = 60% of 400 x

= 240 – 126 = 114 %

= 114/200 * 100 = 57%

DSSSB TGT Social Science Mock Test - 4 - Question 30

Sonam calculates average of 10 positive 2 digit integers. By mistake she interchanges the digits of one number while calculating the average. Because of which, the average becomes 2.7 less than the correct answer. What is the difference between the two digits of the number which was reversed while calculating the average?

Detailed Solution for DSSSB TGT Social Science Mock Test - 4 - Question 30

Let the original number be (10b+a)

  ​​ ​​​​ Because of interchange, the mistaken number is (10a+b)

  ​​ ​​​​ Given that, 10b+a = 10a+b +(2.7*10) => 9b-9a = 27 => b-a = 3

So, the correct answer is A.
