(6-10): The information below provides insights into the population distribution across six different villages (A, B, C, D, E, and F). The bar chart illustrates the number of people in each village, while the table outlines the literacy ratios and the percentage of males residing in these villages.
6. If 40% of the female from village B is literate, then what is the percentage of male, who is illiterate from village B?
A. 38%
B. 35%
C. 37%
D. Cannot be determined
E. None of these
Ans: Option C
→ No. of illiterate female from village B = 60 % (700) = 420
→ No. of illiterate from village B= (9/20)* 2000 = 900
Therefore,
→ No. of illiterate male from village B= 900- 420 =480
→ No. of male from village B = 65 %( 2000) = 1300
→ % of male, who is illiterate from village B = (480/1300) * 100 = 36.9 ≈ 37 (ans)
7. What is the percentage of literate people in all the six villages together?
A. 55%
B. 53%
C. 51%
D. Cannot be determined
E. None of these
Ans: Option B
→ No. of Literate from village A = (2/5)*750 = 300
→ No. of Literate from village B = (11/20)*2000 = 1100
→ No. of Literate from village C = (13/15)*1500 = 1300
→ No. of Literate from village D = (4/5)*2750 = 2200
→ No. of Literate from village E = (1/4)*2500 = 625
→ No. of Literate from village F = (11/30)*3000 = 1100
→ Total no. of literate in all villages= 300+1100+1300+2200+625+1100 = 6,625
→ Total no. of people in all villages= 750+2000+1500+2750+2500+1100 =12,500
→ % of literate people in all villages = (6,625/12,500)* 100 = 53 % (ans)
8. What is the ratio between the number of illiterate people from villages B, C & D to the number of females from villages A, E & F?
A. 320:527
B. 527:330
C. 330:527
D. 527:320
E. None of these
Ans: Option C
→ Illiterate from village B= 2000-1100 =900
→ Illiterate from village C=1500-1300 =200
→ Illiterate from village D= 2750-2200 =550
→ Female from village A= 48% (750) = 360
→ Female from village E= 61% (2500) = 1525
→ Female from village F= 25% (3000) = 750
→ Ratio = (900+200+550) : (360 + 1525+750) = 1650 : 2635 = 330 : 527 (ans)
9. If 3% of females from village D and 5% of females from village E are literate, then what is the total number of literate males from D & F together?
A. 1823
B. 1723
C. 1623
D. Cannot be determined
E. None of these
Ans: Option D
→ Since we don’t have enough data for village F
→ We cannot determine the answer
10. The number of females from villages A & C is how much percentage more or less than the number of females from villages D & F?
A. 24.76%
B. 24.72%
C. 25.76%
D. 25.72%
E. None of these
Ans: Option A
→ Female from village A= 360
→ Female from village C = 825
→ Total = 1185
→ Female from village D= 825
→ Female from village F= 750
→ Total= 1575
→ Less% = [(1575 – 1185) /1575] * 100 = (390/1575)* 100 = 24.76 % (ans)

(16-20): Study the given table carefully to answer the following questions.
| Field Name | Shape | Side (in m) | Base (in m) | Height (in m) | Radius (in m) | Cost of flooring (in Rs. per sq. metre) | Cost of fencing (in Rs. per m) |
|---|---|---|---|---|---|---|---|
| A | Triangle | 16 | 12 | 50 | 20 | ||
| B | Rectangle | 10 × 20 | 30 | 15 | |||
| C | Square | 15 | 40 | 18 | |||
| D | Parallelogram | 20 | 12 | 60 | 25 | ||
| E | Circle | 10 | 45 | 22 |
Q16. What is the cost of flooring of A?
a) Rs.4000
b) Rs.4600
c) Rs.4800
d) Rs.5000
e) Rs.4400
Ans:
So, area of A = 1/2 × 16 × 12 = 96 m2
So, cost of flooring of A = 96 × 50 = Rs.4800
Q17. What is the difference between the cost of fencing of C and that of B?
a) Rs.180
b) Rs.120
c) Rs.240
d) Rs.360
e) Rs.480
Ans:
So, cost of fencing of B = 60 × 15 = 900
Perimeter of C = 4 × 15 = 60 m
So, cost of fencing of C = 60 × 18 = Rs.1080
So, required difference = 1080 – 900 = Rs.180
Q18. What is the ratio of the cost of flooring to that of fencing of field D?
a) 4 : 1
b) 6 : 1
c) 8 : 1
d) 9 : 1
e) 5 : 1
Ans: Option D
Area of D = Base × Height
= 20 × 12 = 240m2
So, cost of flooring of D= 240 × 60 = Rs.14400
Perimeter of D = 2 (20 + 12) = 64 m
So, cost of fencing of D = 64 × 25 = Rs.1600
So, required ratio = 14400 : 1600 = 9 : 1
Q19. The cost of fencing of field E is approximately what percent of the cost of flooring of field C?
a) 10.5%
b) 19.46%
c) 18.71%
d) 15.36%
e) 13.82%
Ans: Option D
Perimeter of E = 2πr = 2 × 22 / 7 × 10 = 440 / 7 m
Cost of fencing of E = 440 / 7 × 22 = Rs.1382.85
Area of C = (15)2= 225m2
So, cost of flooring of C = 225 × 40 = Rs.9000
So, required % = 1382.85 × 100 / 9000
= 15.36% of flooring cost of C.
Q20. The cost of fencing of field C is what percent of the cost of fencing of field D?
a) 87.54%
b) 67.5%
c) 72.13%
d) 54.36%
e) 46.5%
Ans: Option B
Fencing cost of C = Rs.1080
Fencing cost of D = Rs.1600
Required % = 1080 / 1600 × 100 = 67.5%
