Directions (Q. 6 – 10): What value should come in the place of question mark (?) in the following questions?
(3/7) of ? – (2/5) of (13/16) of 2160 = 12 % of 900
Correct
Answer d
(3/7)*x – (2/5)*(13/16)*2160 = (12/100)*900
(3x/7) – 702 = 108
(3x/7) = 108 + 702
(3x/7) = 810
X = (810*7/3) = 1890
Incorrect
Answer d
(3/7)*x – (2/5)*(13/16)*2160 = (12/100)*900
(3x/7) – 702 = 108
(3x/7) = 108 + 702
(3x/7) = 810
X = (810*7/3) = 1890

Three pipes A, B and C can fill a tank in 12 hours. After working at it together for 3 hours, then C is closed and A and B can fill the remaining part in 15 hours. How much time taken by C to fill the tank alone?
Correct
Answer a
Three pipes A, B and C can fill a tank in 12 hours.
A, B and C’s 1 hour work=1/12
A, B and C’s 3 hour work= 3/12
Remaining work= 1- 1/4 =3/4
The remaining part will be filled by A and B in 6 hours. Then,
= > (3/4) *(A+B) = 15
= > (A+B)’s whole work= 20 hr
(A+B)’s 1 hour work= 1/20
A, B and C’s 1 hour work=1/12
C’s 1 hour work= (A+B+C)-(A+B)
= > (1/12) – (1/20)
= > 1/30
C can fill the tank in 30 hours.
Incorrect
Answer a
Three pipes A, B and C can fill a tank in 12 hours.
A, B and C’s 1 hour work=1/12
A, B and C’s 3 hour work= 3/12
Remaining work= 1- 1/4 =3/4
The remaining part will be filled by A and B in 6 hours. Then,
= > (3/4) *(A+B) = 15
= > (A+B)’s whole work= 20 hr
(A+B)’s 1 hour work= 1/20
A, B and C’s 1 hour work=1/12
C’s 1 hour work= (A+B+C)-(A+B)
= > (1/12) – (1/20)
= > 1/30
C can fill the tank in 30 hours.
Question 13 of 20
13. Question
Five years hence, the ratio of Jeevitha and Janvi will be 5:3. The age of Jeevitha, ten years hence is equal to three times of present age of Janvi. What is the present age of Jeevitha?
Correct
Answer c
Five years hence, the ratio of Jeevitha and Janvi = 5:3(5x, 3x)
According to the question,
5x + 5 = 3*(3x – 5)
5x + 5 = 9x – 15
4x = 20
X = 5
The present age of Jeevitha = 5x – 5 = 25 – 5 = 20 years
Incorrect
Answer c
Five years hence, the ratio of Jeevitha and Janvi = 5:3(5x, 3x)
According to the question,
5x + 5 = 3*(3x – 5)
5x + 5 = 9x – 15
4x = 20
X = 5
The present age of Jeevitha = 5x – 5 = 25 – 5 = 20 years
Question 14 of 20
14. Question

And after 3 months, A and B invested 40 % and 25 % more than the initial investment. Find the share of C, if the total profit at the end of the year is Rs. 53820?
A shopkeeper marked up the price of a bed 30% above the cost price and then allowed 20% discount on it. What is the cost price of the bed if he earns a profit of Rs. 300?
Correct
Answer d
Let the cost price be x,
MP = (130/100)*x = (13x/10)
SP = (13x/10)*(80/100) = (26x/25)
Profit = SP – CP
(26x/25) – x = 300
26x – 25x = 300*25
X = 7500
Cost price of bed = Rs. 7500
Incorrect
Answer d
Let the cost price be x,
MP = (130/100)*x = (13x/10)
SP = (13x/10)*(80/100) = (26x/25)
Profit = SP – CP
(26x/25) – x = 300
26x – 25x = 300*25
X = 7500
Cost price of bed = Rs. 7500

16. Question
Directions (Q. 16 – 20) Study the following information carefully and answer the given questions:
Following line graph shows the prices (Per tiles) of four types of tiles P, Q, R and S in different years in a certain company.
If the total number of Q type tiles manufactured in the year 2014 and 2016 is 12000 and 17000 respectively, then find the total cost of Q type tiles in the year 2014 is approximately what percentage more/less than the total cost of Q type tiles in the year 2016?
Correct
Answer a
The total number of Q type tiles manufactured in the year 2014 = 12000
The total price per tiles of Q type tiles manufactured in the year 2014 = Rs. 290
Total cost of Q type tiles in the year 2014 = 12000*290 = 3480000
The total number of Q type tiles manufactured in the year 2016 = 17000
The total price per tiles of Q type tiles manufactured in the year 2016 = Rs. 300
Total cost of Q type tiles in the year 2016 = 17000*300 = 5100000
Required % = [(5100000 – 3480000)/5100000]*100
= > 31.76 % = 32 % less
Incorrect
Answer a
The total number of Q type tiles manufactured in the year 2014 = 12000
The total price per tiles of Q type tiles manufactured in the year 2014 = Rs. 290
Total cost of Q type tiles in the year 2014 = 12000*290 = 3480000
The total number of Q type tiles manufactured in the year 2016 = 17000
The total price per tiles of Q type tiles manufactured in the year 2016 = Rs. 300
Total cost of Q type tiles in the year 2016 = 17000*300 = 5100000
Required % = [(5100000 – 3480000)/5100000]*100
= > 31.76 % = 32 % less

= > 320 + 360 + 350 + 380 + 275 + 370
= > 2055
Required % = (1415/2055)*100 = 68.85 % = 69 %
Incorrect
Answer d
Total price per tiles of P type tiles of all the given years together
= > 240 + 260 + 220 + 270 + 200 + 225
= > 1415
Total price per tiles of R type tiles of all the given years together

The total price per tiles of Q type tiles in the year 2012, 2014 and 2016 together
= > [280 + 290 + 300]
= > 870
Required difference = 1050 – 870 = 180
Incorrect
Answer c
The total price per tiles of S type tiles in the year 2013, 2015 and 2017 together
= > [320 + 340 + 390]
= > 1050
The total price per tiles of Q type tiles in the year 2012, 2014 and 2016 together

If the total number of R type tiles manufactured in the year 2013 and 2016 is 17000 and 11000 respectively, then find the average revenue of R type tiles in the year 2013 and 2016 together?
Correct
Answer c
The total number of R type tiles manufactured in the year 2013 = 17000
Total revenue of R tiles in the year 2013
= > 17000*360 = 6120000
The total number of R type tiles manufactured in the year 2016 = 11000
Total revenue of R tiles in the year 2016
= > 11000*275 = 3025000
Required average = (6120000 + 3025000)/2
= > 4572500
