DSSSB TGT Social Science Mock Test - 5 - Question 14

There are three galleries in a coal mine. On the first day, two galleries are operative and after some time, the third gallery is made operative. With this, the output of the mine became half as large again. What is the capacity of the second gallery as a percentage of the first, if it is given that a four-month output of the first and the third galleries was the same as the annual output of the second gallery?

Detailed Solution for DSSSB TGT Social Science Mock Test - 5 - Question 14

The third gallery making the capacity ‘half as large again’ means an increase of 50%.

Further, it is given that: 4(first + third) = 12 (second) In order to get to the correct answer, try to fit in the options into this situation.

(Note here that the question is asking you to find the capacity of the second gallery as a percentage of the first.)

If we assume option (a) as correct – 70% the following solution follows:
If the second is 70, then first is 100 and the first + second is 170. Then third will be 85 (50% of first + second).

Then the equation:
4 X (100 + 85) should be equal to 12 X 70
But this is not true.

Through trial and error, you can see that the third option fits correctly.
4 X (100 + 80) = 12 X 60.
Hence, it is the correct answer.

DSSSB TGT Social Science Mock Test - 5 - Question 15

A sum amounts to Rs. 882 in 2 years at 5% compound interest. The sum is 

Detailed Solution for DSSSB TGT Social Science Mock Test - 5 - Question 15

Compound interest = Amount -Principal
Amount = P(1 + R/100)N 
882 = P(1+5/100)2
=  882 × 20/21 × 20/21 
P = 800
 

DSSSB TGT Social Science Mock Test - 5 - Question 16

Detailed Solution for DSSSB TGT Social Science Mock Test - 5 - Question 16

DSSSB TGT Social Science Mock Test - 5 - Question 17

Ratio between present ages of A, B and C is 5:4:6. Total of the ages of A and C after 5 years will be 54 years. What will be the ratio of ages of B and C after 4 years?

Detailed Solution for DSSSB TGT Social Science Mock Test - 5 - Question 17

Option (2) 5:7 is correct✅answer. 

Explanation:-

Let age of A = 5 x

                   B=  4x

                   C = 6x 

Then, according to the question;

( 5x+5) + (6x+5) = 54

11x + 10   = 54

=> 11x  = 54-10

=> 11x = 44

=> x =  4

B's age after 4 years;

 = 4x +4 

=> 4*4+4 

=>  20 years. 

C's age after 4 years ;

= 6x+4 

=>6*4+4

=  28 years 

Therefore,  ratio = 20/28

=>       ratio = 5:7

DSSSB TGT Social Science Mock Test - 5 - Question 19

8 men can do a work in 12 days. After 6 days of work four more men were employed. In how many days would the remaining work be done. 

Detailed Solution for DSSSB TGT Social Science Mock Test - 5 - Question 19

The correct option is C.
let 1 men does 1 unit of work per day
So Total work: 8x12=96units 
Work 8 men will do in 6 days =8x6=48 units. 
work lelt =96−48=48 units 
After 6 days 4 men join. 
so total men is 12 men (8+4) they will do 12 unit of work per day 
Now,
remaining work completed in 
=48/12
= 4 days

DSSSB TGT Social Science Mock Test - 5 - Question 20

Anu sold 2 books at Rs. 1.40 each. Her profit on one was 20% and her loss on the other was 20%. Then she made

Detailed Solution for DSSSB TGT Social Science Mock Test - 5 - Question 20

By apply percentage effect. 20% - 20% - 20×20/100 = 4% loss occur. S.P of both books= 2.8 Rs = 100 - 4 = 96% of C.P. So, 2.8 = 96% , C.P 100% = 2.8×100/96 = 2.917. C.P - S.P = 2.917 - 2.8 = .117 = 12 paise

DSSSB TGT Social Science Mock Test - 5 - Question 21

 Study the following graph carefully to answer the given questions

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

A waste pipe, W can carry off 12 litre of water per minute. If all the pipes I, J and W are opened when the tank is full and it takes one hour to empty the tank. Find the capacity of the tank.

Detailed Solution for DSSSB TGT Social Science Mock Test - 5 - Question 21

Let the waste pipe take ‘T’ time to empty the tank.
(1/10 + 1/12 – 1/T)*60 = -1
We will get T = 5 min
So capacity = 5*12 = 60ltr

Detailed Solution for DSSSB TGT Social Science Mock Test - 5 - Question 22

down stream speed of boat on Tuesday and Friday = 32 kmph
Still water speed = 25 kmph
Difference = 32 – 25 = 7 kmph

DSSSB TGT Social Science Mock Test - 5 - Question 24

A retailer sold 12 notes at a profit of 20% and 8 notes at a profit of 10%. If he had sold all the 20 notes at a profit of 15%, then his profit would have been reduced by Rs.36. What is the cost price of each note?

Detailed Solution for DSSSB TGT Social Science Mock Test - 5 - Question 24

Answer - D.Rs.180
Explanation :
Cost Price = x
Total Profit
= 12x * 20/100 + 8x * 10/100 = 320x/100 = 3.2x
= 20x * 15/100 — (ii) Profit of 15% on 20 notes
Total Profit
3.2x - 3x = 36
0.2x = 36
x = 180

(1/20 + 1/16)*t = 1/2

DSSSB TGT Social Science Mock Test - 5 - Question 29

The product of two numbers is 2028 and their H.C.F. is 13. The number of such pairs is:

Detailed Solution for DSSSB TGT Social Science Mock Test - 5 - Question 29

Let the numbers 13a and 13b.
Then, 13a x 13b = 2028
⇒ ab = 12.
Now, the co-primes with product 12 are (1, 12) and (3, 4).
[Note: Two integers a and b are said to be coprime or relatively prime if they have no common positive factor other than 1 or, equivalently, if their greatest common divisor is 1 ]
So, the required numbers are (13 x 1, 13 x 12) and (13 x 3, 13 x 4).
Clearly, there are 2 such pairs.
