Quantitative Aptitude: Data Interpretation Questions Set 155

Directions : The given below table shows that the number of boys and girls studied in five different classes.

1. No. of boys in class A and B together is how many more or less than no. of girls in class C and E together ?
   65
   38
   52
   48
   50
   Option E
   Total no. of boys in class A and B = 48 + 76 = 124
   total of no. of girls in class C and E = 80 + 94 = 174
   difference = 174 – 124 = 50

    

2. What is the ratio of total no. of girls in class B and no. of boys in class D ?
   17 : 19
   15 : 19
   6 : 5
   3 : 4
   19 : 17
   Option E
   Ratio = 38 : 34 = 19 : 17

    

3. No. of boys in class A and C together is what percent more or less than than the no. of girls in class C ?
   50%
   40%
   46%
   56%
   64%
   Option B
   Total no. of boys in class A and C together = 48 + 64 = 112
   girls in class C = 80
   percentage = more = 112 – 80 / 100 = 40%

    

4. What is difference between total no. of students in class D and total no. of students in class A ?
   18
   25
   34
   46
   52
   Option A
   Total students in class D = 34 + 58 = 92
   total students in class A = 48 + 62 = 110
   difference = 110 – 92 = 18

    

5. Total no. of students in class F is 20% more than the total no. of students in class A. If ratio of boys and girls in class F is 2 : 1 , then find total no. of boys in class F and E together.
   125
   170
   280
   240
   270
   Option B
   Total students in class A = 110
   total students in class F = 110 * 6/5 = 132
   boys in class F = 132 * 2/3 = 88
   total boys in class F and E = 88 + 82 = 170

    

Directions : The following pie-chart given below shows that the percentage distribution marks of six different subjects scored by Ram.


6. 
   Difference between total marks scored by Ram in Math and Economics together to total marks scored in English and Chemistry together ?
   35
   46
   68
   54
   82
   Option D
   Total marks in Math and Economics together = 1800 * (20% + 15%)/100 = 630
   Total marks in English and Chemistry together = 1800 * (10% + 22%)/100 = 576
   difference = 630 – 576 = 54
   

    

7. What is the ratio between marks scored by Ram in Physics and in Economics ?
   3 : 2
   1 : 5
   2 : 3
   5 : 4
   2 : 5
   Option D
   Ratio = 25% : 20% = 5 : 4
   

    

8. Total marks scored in Math is what percent more or less than total marks scored in History ?
   67.5%
   28.4%
   87.5%
   92.25%
   50%
   Option C
   Percentage = 15% – 8% / 8% = 100 = 87.5%

    

9. Total marks scored by Ram in Physics and Math together how much more or less than total marks scored in History and Economics together ?
   220
   320
   540
   216
   175
   Option D
   Total marks in Physics and Math together = 1800 * (15 + 25)/100 = 720
   Total marks in Physics and Economics together = 1800 * (20 + 8)/100 = 504
   Difference = 720 – 504 = 216
   

    

10. What is the central angle of marks scored by Ram in English ?
    82 degree
    36 degree
    144 degree
    72 degree
    40 degree
    Option B
    Central angle = 10/100 * 360 = 36 degree
