Quantitative Aptitude-More exercise questions updated on Jan 2020
Fractions tell how many parts of a whole we have. We have a top number, the numerator, and a bottom number, the denominator. For example, 1/2 is a fraction. Well, if we picture a pizza, the bottom number tells us how many slices to slice the pizza, and the top number tells us how many of those slices we can have. So 1/2 tells us that we have sliced our pizza into two slices, and we can take 1 of those slices.

1. Exp: 20.05 + 35.603- 43.087 = 55.653- 43.087= 12.566

2. Exp: 23 =0.821

28

14 = 0.933

15

15 = 0.7894

19

21  = 0.875

24

So, 15 = 0.7894 is smallest.

19

3. Exp: 0.585858= = 58

99

4. Exp: = 3+ = 3+236-1 = 3 47/198

990

5. Exp: 9*7=63

Sum of decimal places= 4

So, 0.9*0.007=  0.0063

6. Exp: Let 0.0015 = 0.003

X

X= 0.0015 = 0.5

0.003

7. Exp: Given Expression= 0.363*(0.522+0.478)= 0.363*1= 0.363

8. Exp: Given 7125  = 5700
1.25

712.5 =71.25 = 7125*1  = 5700 = 57

12.5       1.25     1.25*100   100

9. Exp: 34.31*0.473*1.567 = 25.4303 = 2.15

0.0673*23.25*7.57      11.845

10. Exp. Given Expression = a2-b2 = (a+b) (a-b) = (a+b)

a-b           a-b

(5.68)2 – (4.32)2 =   (5.68+ 4.32) = 10

5.68- 4.32

11. Exp: Given Expression = a3+b3      =(a+b)

a2-ab+b2

= (4.3+1)= 5.3

12. Exp: 5 5       = 5*2.24          = 11.2       =11.2 = 14

4 5-.96     4*2.24-.96      8.96-.96        8

13. Exp: 10k = 0.0551 = 5.51  = 5.51* 102 = 1 = 10-2

5.51       551      551* 102    102

14. Exp: 25.25 = 2525 = 0.012625

2000    200000

15. Exp: (2.502+0.064)2 - (2.502-0.064)2  = (a+b)2 - (a-b)2  = 4ab  = 4

2.502*0.064                              ab              ab

16. Exp: 4.5*1.8+4.5*8.2 = 4.5 (1.8+8.2) = 4.5*10 = 45 =3

1.5*4.5+1.5*5.5     1.5 (4.5+5.5)  1.5*10  15

17. Exp: (.02)2 + (0.52)2 + (0.035)2  =          a2+b2+c2

(0.002)2 + (0.052)2 + (0.0035)2     ( a /10) 2+ ( b/10) 2 + ( c/10) 2  ,

where a= .02, b= .52, c= .035

= 100(a2+b2+c2) = 100

a2+b2+c2

18. Exp: Number of men donors= 200*1/4 =50

Number of women donors=200-50=150

1 man donor donates = Rs.3000

Therefore,  50 men donor donates = 3000* 50= Rs.1,50,000

1 woman donor donates= 3000*1/2 = Rs.1500

Therefore, 150 women donor donates = 1500* 150= Rs.2,25,000

Hence total amount collected = 1,50,000+ 2,25,000

= Rs.3,75,000

19.  Let the saving be Rs. x

Therefore, Expenditure = Rs. (6300-x)

then, (6300-x)* 1 = x* 1

5         2

=> 1260- x = x

5    2

=> 1260= x + x

2      5

=> 7x = 1260

10

x= 1800

20. Exp: Let the length of the hall be x m

Breadth of the hall = 1x  m

2

Area of the hall = Length * Breadth

450  = x * 1x

2

x²   = 900

x  =30

Difference between the length and breadth of the hall = x - 1x  = x/2

2

30 = 15m

Fractions tell how many parts of a whole we have. We have a top number, the numerator, and a bottom number, the denominator. For example, 1/2 is a fraction. Well, if we picture a pizza, the bottom number tells us how many slices to slice the pizza, and the top number tells us how many of those slices we can have. So 1/2 tells us that we have sliced our pizza into two slices, and we can take 1 of those slices.
