1). Answer: c)
Explanation:
Total number of females of village Q = (40/100)*48000 = 19200
Number of literate females = (30/100)*19200 = 5760
Total number of literate population of village Q = (7/12)*48000 = 28000
Number of literate males = 28000 – 5760 = 22240
2). Answer: b)
Explanation:
Total number of rich population of village P = (3/5)*35000 = 21000
Total number of females of village T = [(100 – 30)/100]*30000 = 21000
Required percentage = (21000/21000)*100 = 100 %
3). Answer: d)
Explanation:
Rich population of,
P = (3/5)*35000 = 21000
Q = (5/6)*48000 = 40000
R = (4/9)*45000 = 20000
S = (1/2)*32000 = 16000
T = (3/5)*30000 = 18000
U = (2/5)*25000 = 10000
Required sum = 21000 + 40000 + 20000 + 16000 + 18000 + 10000 = 125000
4). Answer: a)
Explanation:
Number of males of village S = (40/100)*32000 = 12800
Number of literate population of village S = (¾)*32000 = 24000
Number of literate males = (2/5)*24000 = 9600
Number of illiterate males = 12800 – 9600 = 3200
5). Answer: d)
Explanation:
Literate population of village R = (3/5)*45000 = 27000
Poor population of village U = (3/5)*25000 = 15000
Required percentage = [(27000 – 15000)/15000]*100 = 80 %
Explanation:
Total number of females of village Q = (40/100)*48000 = 19200
Number of literate females = (30/100)*19200 = 5760
Total number of literate population of village Q = (7/12)*48000 = 28000
Number of literate males = 28000 – 5760 = 22240

Explanation:
Total number of rich population of village P = (3/5)*35000 = 21000
Total number of females of village T = [(100 – 30)/100]*30000 = 21000

Explanation:
Rich population of,
P = (3/5)*35000 = 21000
Q = (5/6)*48000 = 40000
R = (4/9)*45000 = 20000
S = (1/2)*32000 = 16000
T = (3/5)*30000 = 18000

Required sum = 21000 + 40000 + 20000 + 16000 + 18000 + 10000 = 125000

Number of literate population of village S = (¾)*32000 = 24000
Number of literate males = (2/5)*24000 = 9600
Number of illiterate males = 12800 – 9600 = 3200
5). Answer: d)
Explanation:
Literate population of village R = (3/5)*45000 = 27000
Poor population of village U = (3/5)*25000 = 15000

1) Answer: c)
Required sum = 5 x 9 + 8 x 12 + 10 x 20 + 6 x 10
= 45 + 96 + 200 + 60
= 401 Km
2) Answer: a)
Speed of stream on Sunday = (18-10)/2 = 4 kmph
Speed of stream on Monday = (15-9)/2 =3 kmph
Speed of the boat on Tuesday = (20+10)/2 = 15 kmph
Speed of the boat on Wednesday = (10+6)/2 = 8 kmph
Sum of the speeds of the stream on Sunday and Monday together = 4 + 3 = 7 km/h
Sum of the speed of the boats in normal water on Tuesday and Wednesday together
= 15 + 8
= 23 km/h
Required percentage = 7/23 x 100 = 30.43%
3) Answer: d)
Speed of stream on Thursday = (15-7)/2= 4 kmph
Speed of boat O = (12+6)/2= 9 kmph
Required ratio = 4:9
4) Answer: a)
Sum of downstream speed of all the boats = 18 + 15 + 20 + 10 + 15 + 12 + 7
= 97 km/h
Sum of upstream speed of all the boats = 10 + 9 + 10 + 6 + 7 + 6 + 5
= 53 km/h
Required difference = 97 – 53 = 44 kmph
5) Answer: c)
Speed of boat J = (18+10)/2 = 28/2 =1 4 kmph
Speed of boat P = (7+5)/2 = 6 kmph
Required percentage = (14 – 6)/6 x 100
= 8/6 x 100
= 133.33% more
Required sum = 5 x 9 + 8 x 12 + 10 x 20 + 6 x 10
= 45 + 96 + 200 + 60
= 401 Km
2) Answer: a)
Speed of stream on Sunday = (18-10)/2 = 4 kmph
Speed of stream on Monday = (15-9)/2 =3 kmph
Speed of the boat on Tuesday = (20+10)/2 = 15 kmph
Speed of the boat on Wednesday = (10+6)/2 = 8 kmph
Sum of the speeds of the stream on Sunday and Monday together = 4 + 3 = 7 km/h
Sum of the speed of the boats in normal water on Tuesday and Wednesday together
= 15 + 8
= 23 km/h
Required percentage = 7/23 x 100 = 30.43%
3) Answer: d)
Speed of stream on Thursday = (15-7)/2= 4 kmph
Speed of boat O = (12+6)/2= 9 kmph
Required ratio = 4:9
4) Answer: a)
Sum of downstream speed of all the boats = 18 + 15 + 20 + 10 + 15 + 12 + 7
= 97 km/h
Sum of upstream speed of all the boats = 10 + 9 + 10 + 6 + 7 + 6 + 5
= 53 km/h
Required difference = 97 – 53 = 44 kmph
5) Answer: c)
Speed of boat J = (18+10)/2 = 28/2 =1 4 kmph
Speed of boat P = (7+5)/2 = 6 kmph
Required percentage = (14 – 6)/6 x 100
= 8/6 x 100
= 133.33% more
