Quantitative Aptitude Aptitude questions and answers for interview preparation

we check according to the wers for eg. 14x4=56 and 1x2=2 then also total 58 wheel thus 14 is the max no of 4 wheelers.
But less than 14 also possible so goes through the option.

our number is xy9 

now if x is 0 then y has 10 options 

now if x is 1 then y has 9 options (except 9) 
now if x is 2 then y has 8 options (except 9 and 8) 

now if x is 9 then y has 1 option (that is 0)

If there are 5 questions, and only 3 question are slected, that is 10 different possible combinations. There 3 section, and with each section having 10 possible combinations, give 1000 different possible combinations.

it will take 38mins to reach 60meters. 
at 39th min it will b back at 57meters and again at 40th min it will be back at 60meters.

Ans: 3

When the number is divided by 3D we got 2@Me the number itself is 21 and 3D >21.

when 21/D, remainder is 8.

So D = 21-8 =13.

now (21*2)/(13*3), Remainder is 3.

Make two cuts to divide the cake into 4 (cutting on the diameter of a circular cake, the cuts perpendicular to each other). Now, place the 4 sectors of the cake one over the other. Make a cut such that the cut goes throw the centre cutting each of the cake sectors into half. So now we have done 3 cuts. Each sector is cut into two so 4*2=8.

Given that there are 8 Prime Numbers under 20, and if the limit is only random numbers under 20 then there is a 40% chance of getting a prime number.

 4.5 kms

54 kilometers per hours = 54000 meters per hour
54000 meters / 60 minutes = 900 meters per minute
900 meters * 5 minutes of traveling time = 4500 meters travel
4500 meters = 4.5 kilometers traveled in 5 minutes

car/2wheeler=1/8,suppose car be X & 2wheeler be Y.

X/Y=1/8; Y=8X also there r 4 tyre in 1 car & 2 tyre in 1 two wheeler ;

therefore 4X + 2Y=100

Solving these 2 eq. X=5 & Y=40.

There are 78125 8 digit numbers form from the numbers 1, 2, 3, 4, and 5 that are evenly divisionable by @I think thats just a few too many than could be listed here.


= 25

bcoz, 3*3=9





so like(3*6 and 3*7 it will be 5*4 and 5*5 mens increment by 1)

The six weights will be 1 kg, 3kg,9kg, 27kg, 81 kg, and 243kg.for instance to weigh 2kg= 3kg-1kg...and so on for all the weights.

among 3 socks she has to choose 2 black socks from 9 pair(=18) of black socks, that can be done in 18C2 ways. and the third sock can be chosen from among the remaining socks that can be done in ((8+9-1)x2 )C 1 ways i.e. in 32 ways.

. 32 X 18C2.

No. of Cats: 163, 613, or 99919
-- Local variables here
i integer;
-- Test statements here
for i in 1..99919 loop
if mod(99919,i) = 0 then
dbms_output.put_line (i);
end if;
end loop;

If you paint the cube such that:

  • Blue and Blue are on opposite sides
  • Red and Red are on opposite side
  • Yellow and Yellow are on opposite side
  • And, since the question didnt state where the 32 smaller could be, Im placing the 32 smaller cubes on the sides with Blue paint.
  • Thus: 32 cubes have Blue on at least one side.
  • 20 cubes have have colors on two sides.

The 4cm cube is divide into 125 smaller cubes:

that me that the 4cm cube = 5 smaller cubes in height, width, and depth 

Also, given that the 4cm is painted red on all six side:

  • only those smaller cubes that touch no outer surface will be free of red paint,
  • 27 smaller cubes have no red paint on them.
  • 98 smaller cubes have some red paint on them.





40+24-15 =1/x





x=2 22/49 in fraction

4/5 full tank= 12 miles.
1 full tank= 12/(4/5).
1/3 full tank= 12/(4/5)*(1/3)= 5 miles.

(log a + log b)(log a- log b) =log ab . log a/b

300 in the nigiets base 8
192 in the base 10 for us ....
The wer is total of 192 (base 10)

Train crossed the car with less speed in less time and the car with high speed in more time.i.e train and two cars going in the same direction.

hence 1st car

L/((S-45)*5/18)=36 i.e L=10S-450

similarly for 2nd car


BY solving these two equations we get length of the train L=150mtrs

Exactly 24 days... 

1 man do 1/44 job per day.

2 woman do 1/44 job per day.

3 children do 1/44 job per day.


1man , 1 woman , 1 child.

1/44+1/88+1/132 job per day 

so 11/264 = 1/t where t is the time taken.

now 264/11 = 24 = t

only those smaller cubes that do not touch the edges of the 4cm cube will have only one side painted, thus:

- 54 smaller cubes have only one side painted

- 36 smaller cubes have two sides painted

- 8 smaller cubes have three sides painted
