Answers and Explanations

1. Answer – Option C

Explanation –

Number of boys = 600

Number of girls = 800

Subjects Girls Boys
Zoology 30 x 8 = 240 290 – 240 = 50
Botany 220 – 120 = 100 20 x 6 = 120
Mathematics $$\frac {2}{5}$$ x 250 = 100 $$\frac {3}{5}$$ x 350 = 150
Physics 200 200
Statistics 20 x 8 = 160 $$\frac {160}{2}$$ = 80

Required answer = 200 + 200 + 160 + 80 = 640

2. Answer – Option D

Required ratio = 150 : 100 = 3:2

3. Answer – Option A

Explanation –

Required difference = 100 – 50 = 50

4. Answer – Option D

Explanation –

Zoology and statistics

5. Answer – Option C

Explanation –

E. None of these

Answers and Explanations

1. Answer – Option C

Explanation –

→ No. of illiterate female from village B = 60 % (700) = 420

→ No. of illiterate from village B = $$(\frac {9}{20}) \times 2000 = 900$$

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 = $$(\frac {480}{1300}) \times 100$$ = 36.9 ≈ 37

2. Answer – Option B

Explanation –

→ No. of Literate from village A = $$(\frac {2}{5}) \times 750$$ = 300

→ No. of Literate from village B = $$(\frac {11}{20}) \times$$ 2000 = 1100

→ No. of Literate from village C = $$(\frac {13}{1}) \times$$ 1500 = 1300

→ No. of Literate from village D = $$(\frac {4}{5}) \times$$ 2750 = 2200

→ No. of Literate from village E = $$(\frac {1}{4}) \times$$ 2500 = 625

→ No. of Literate from village F = $$(\frac {11}{30}) \times$$ 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 = $$(\frac {6625}{12500}) \times$$ 100 = 53 %

3. Answer – Option C

Explanation –

→ 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)

4. Answer – Option D

Explanation –

→ Since we don’t have enough data for village F

→ We cannot determine the answer

5. Answer – Option A

Explanation –

→ 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% = $$[\frac {(1575 – 1185)} {1575}] \times 100 = (\frac {390}{1575}) \times 100 = 24.76$$ %

E. 174%

Answers and Explanations

1. Answer – Option

Explanation –

Average expenses of P

= (10% Of $$\frac {96}{360}$$ + 30 % of $$\frac {129}{360}$$ + 10% of $$\frac {36}{360}$$ + 40% of $$\frac {51}{360}$$ + 20% of $$\frac {48}{360}$$) $$\times \frac {120000}{5}$$

= $$\frac {960 + 3870 + 360 + 2040 + 960}{3600 } \times \frac {120000}{5}$$

= Rs. 5460

2. Answer – Option A

Explanation –

Amount spent by Rahul on Entertainment

$$\frac {20}{100} \times \frac {36}{360} \times 120000 = Rs 2400$$

Amount spent by Preeti on Entertainment

$$\frac {15}{100} \times \frac {36}{360} \times 120000 = Rs 1800$$

∴ Required percentage increase

$$\frac {2400 – 1800}{1800} \times 100 = 33$$%

3. Answer – Option D

Explanation –

Average expenses of Rohit

= $$(25% Of [latex]\frac {96}{360}$$ + 15 % of $$\frac {129}{360}$$ + 25% of $$\frac {36}{360}$$ + 10% of $$\frac {51}{360}$$ + 10% of $$\frac {48}{360}$$) $$\times$$ 120000

= $$\frac {2400 + 1935 + 900 + 510 + 480}{36000 } \times \frac {120000}{5}$$

= Rs 4150

Average expenses of W (wife)

= $$(15% 0f \frac {96}{360} + 25 % of \frac {129}{360} + 30% of \frac {36}{360} + 10% of \frac {51}{360} + 25% of \frac {48}{360}) \times \frac {120000}{5}$$

= $$\frac {1440 + 3225 + 1080 + 510 + 1200}{36000} \times \frac {120000}{5}$$

= Rs 4970

∴ Required percentage

= $$\frac {4150}{4970} \times 100 = 83.5$$%

4. Answer – Option A

Explanation –

Required difference

= ((10 + 15) of $$\frac {96}{360}$$ – (30 + 10)% of $$\frac {36}{360}$$) $$\times \frac {120000}{2}$$

= $$\frac {2400 – 1440}{36000} \times \frac {120000}{5} = Rs.1600$$

∴ Required percentage

= $$\frac {1600}{120000} \times 100 = 1.3$$%

5. Answer – Option C

Explanation –

Required percentage

$$\frac {20 \times 129 + 25 \times 51}{960 + 1290} \times 100$$

$$\frac {2580 + 1275}{960 + 1290} \times 100 = \frac {3855}{2250} \times 100 = 171$$%
