Direction(1-5): Study the following graph carefully and answer the following questions given below.
Q1
If the ratio of number of boys & girls are in the ratio 3:2 in N and P, find the average number of boys in N and P together ?
- A. 377.15
B. 379.25
C. 320.75
D. 397.5
N : 675 [latex]\Rightarrow Boys = 675 \times \frac {3}{5} = 405[/latex]
P : 650 [latex]\Rightarrow Boys = 650 \times \frac {3}{5} = 390[/latex]
Avg = [latex]405 + \frac {390}{2} = 397.5[/latex]
Q2
Find the total no of failed students in M, O and Q together ?
- A. 247
B. 330
C. 341
D. 430
M = [latex]768 \times 25% = 192[/latex]
O = [latex]460 \times 15% = 69[/latex]
Q = [latex]320 \times 25% = 80[/latex]
Total = 341
Q3
What will be the ratio of number of boys passed in N to number of girls failed in N, if the number of girls and boys in the ratio 16:11 ?
- A. 121 : 24
B. 7 : 11
C. 103 : 529
D. 21 : 37
675 [latex]\Rightarrow 400 : 275 \Rightarrow 16 : 11 = G:B[/latex]
[latex] G : 400 \times 12% = 48[/latex]
[latex]B : 275 \times 88% = 242[/latex]
242 : 48 = 121 : 24
Q4
Find the difference between the number of passed students in Q to number of failed students in M ?
- A. 48
B. 57
C. 27
D. 32
Q Passed [latex]\Rightarrow 75% of 320 = 240[/latex]
M failed [latex]\Rightarrow 192[/latex]
Difference = 240 - 192 = 48
Q5
Which centre has the second least number of failed student ?
- A. M
B. P
C. O
D. Q
M = 192
N = 81
O = 69
P = 130
Q = 80
