Three pipes A, B and C can fill a tank in 18 hours.

A, B and Câ€™s 1 hour work = 1/18

A, B and Câ€™s 6 hour work = 6/18 = 1/3

Remaining work = 1 – 1/3 = 2/3

The remaining part will be filled by A and B in 6 hours. Then,

= > (2/3)*(A+B) = 16

= > (A+B)â€™s whole work = 24 hr

(A+B)â€™s 1 hour work = 1/24

A, B and Câ€™s 1 hour work = 1/18

Câ€™s 1 hour work= (A+B+C) – (A+B)

= > (1/18) â€“ (1/24)

= > 1/72

C can fill the tank in 72 hours.

Perimeter of rectangle = 2*(l + b) = x

2l + 2b = x and 2Ï€r = x + 8

r/l = 1/2 and l/b = 7/3

r : l : b = 7 : 14 : 6 (7y, 14y, 6y)

2Ï€r = x + 8

2Ï€r = 2l + 2b + 8

2*(22/7)*7y = 2*14y + 2*6y + 8

44y = 28y + 12y + 8

44y â€“ 40y = 8

4y = 8

Y = 2

Length of the rectangle = 14y = 28 m

3 years ago, the ratio of ages of Ganesh and Magathi = 3 : 4 (3x, 4x)

Magathiâ€™s age after 4 years = 35 years

Magathiâ€™s present age = 31 years

4â€™s = 28

1â€™s = 7

Ganeshâ€™s present age = 3x + 3 = 24 years

According to the question,

31 + 24 = 7 + Manoâ€™s present age

55 â€“ 7 = Manoâ€™s present age

Manoâ€™s present age = 48 years

The share of P, Q and R

= > [15000*3 + 15000*(140/100)*9] : [18000*12] : [24000*8 + 20000*4]

= > 234000 : 216000 : 272000

= > 117 : 108 : 136

361â€™s = 61370

1â€™s = 170

The share of Q = 108â€™s = Rs. 18360

MP*(80/100) = 250*(112/100)

MP = 250*(112/100)*(100/80)

MP = Rs. 350

SP = 250*(112/100) = 280

Required % = (280/350)*100 = 80 %

Directions (6-10):

The total temperature in Delhi in all the given months together

= > 41 + 43 + 37 + 33 + 29 + 31 = 214Â°C

The total temperature in Hyderabad in all the given months together

= > 44 + 42 + 27 + 29 + 32 + 36 = 210Â°C

Required difference = 214 â€“ 210 = 4Â°C

The total temperature in the month of August in all the given cities together

= > 32 + 43 + 37 + 41 + 42 = 195Â°C

The total temperature in the month of October in all the given cities together

= > 28 + 33 + 36 + 33 + 29 = 159Â°C

Required ratio = 195 : 159 = 65 : 53

The total temperature in the month of December in all the given cities together

= > 38 + 31 + 45 + 27 + 36 = 177Â°C

Required average = 177/5 = 35.4Â°C

The total temperature in Chennai in all the given months together

= > 36 + 32 + 30 + 28 + 34 + 38 = 198Â°C

The total temperature in Lucknow in all the given months together

= > 35 + 37 + 32 + 36 + 43 + 45 = 228Â°C

Required % = (198/228)*100 = 87Â°C

The total temperature in the month of July in all the given cities together

= > 36 + 41 + 35 + 47 + 44 = 203Â°C

The total temperature in the month of November in all the given cities together

= > 34 + 29 + 43 + 29 + 32 = 167Â°C

Required % = (203/167)*100 = 122 %
