Directions (1-5) :

Let the speed of the plane be 3x

Then new speed = 3x * (133.33/100) = 4x

Then

2400 = (2 * 3x * 4x)/x

x = 100

New speed = 4 * 100 = 400 kmph

Relative distance = 48

Relative speed = 63 â€“ 48 = 15

Then,

48 = 15 * time

3.2 h = time

Required distance = 3.2 * 63 = 201.6 km

The ratio of speed of stream and boat = 1: 7 (x, 7x)

[120/(7x – x)] + [120/(7x + x)] = 3.5

35/x = 3.5

x = 10

Required sum = 8 * 10 = 80 kmph

SI = pnr/100

780 = x * 3 * 13/100

x = 2000

1020 = y * 2 * 17/100

y = 3000

Required interest = (2000 + 3000) * 7/100 * 6

= 2100

A = p (1 + r/100)n

A = 2500 (1 + 20/400)4

A = 2500 * 105/100 * 105/100 * 105/100 * 105/100

A = 3038.7656

Directions (6-10) :

The temperature of Chennai and Mumbai together in the month of Jan

= > 32 + 34 = 660 C

The temperature of Chennai and Mumbai together in the month of Apr

= > 41 + 36 = 770 C

Required ratio = 66: 77 = 6 : 7

The temperature of all the given cities in the month of Feb

= > 36 + 33 + 40 = 1090 C

The temperature of all the given cities in the month of May

= > 40 + 46 + 32 = 1180 C

Required difference = 118 â€“ 109 = 90 C

The temperature of Chennai in all the given months together

= > (32 + 36 + 38 + 41 + 40) = 1870 C

The temperature of Mumbai in all the given months together

= > (34 + 40 + 42 + 36 + 32) = 1840 C

Required % = (187 / 184) * 100 = 101.63 % = 102 %

The temperature of all the given cities in the month of Jan

= >32 + 36 + 34 = 1020 C

The temperature of all the given cities in the month of Mar

= >38 + 28 + 42 = 1080 C

Required % = [(108 â€“ 102) / 108] * 100 = 5.55 % = 6 % less

The temperature of Delhi in all the given months together

= > (36 + 33 + 28 + 44 + 46) = 1870 C

The temperatures of Mumbai in all the given months together

= > (34 + 40 + 42 + 36 + 32) = 1840 C

Required difference = 187 â€“ 184 = 30 C
