Quantity II:Â 5 days

A) Quantity I > Quantity II

B) Quantity I â‰¥ Quantity II

C) Quantity I = Quantity II

D) Quantity I < Quantity II

E) Quantity I â‰¤ Quantity II

4 * 2 + 2 = 10

10 * 3 + 3 = 33

33 * 4 + 4 = 136

136 * 5 + 5 =Â 685

685 * 6 + 6 = 4116

1944/2 â€“ 4 = 968

968/2 â€“ 4 = 480

480/2 â€“ 4 = 236

236/2 â€“ 4 = 114

114/2 â€“ 4 =Â 53

88 + 77 = 165

165 + 55 = 220

220 + 33 = 253

253 + 11 =Â 264

85 + 52Â = 110

110 â€“ 42Â = 94

94 + 32Â = 103

103 â€“ 22Â = 99

99 + 12Â =Â 100

Directions (6-10) :

From Quantity I,

Area of the rectangle = 216

3x * 2x = 216

x2Â = 36

x = 6 cm

Perimeter of the rectangle = 2 * (3 * 6 + 2 * 6) = 60 cm

From Quantity II,

Â 63 cm

Quantity I < Quantity II

From Quantity II,

CI = P (1 + R/100)2Â – P

CI = 1800 * (1 + 10/100)2Â â€“ 1800

= 378

From Quantity II,

Difference = 37800 * 10 * 10/(100 * 100)

= 378

Quantity I = Quantity II

From Quantity I,

18 seconds

From Quantity II,

Required time = 180/(20 * 5/18) = 32.4 seconds.

Quantity I < Quantity II

From Quantity I,

(4x + 8)/(5x + 8) = 5/6

25x + 40 = 24x + 48

x = 8 years

A = 4 * 8 = 32 years

B = 5 * 8 = 40 years

After 15 years A and Bâ€™s age is 47 and 55 years respectively.

Difference between the ages of A and B = 8 years

From Quantity II,

6 years

Quantity I > Quantity II

From Quantity I,

A = 1/10

B = 1/18

C = 18 * 100/150 = 12 days

A + B + C = 1/10 + 1/18 + 1/12

= (18 + 10 + 15)/180

= 43/180

Required time = 180/43 days

From Quantity II,

5 days

Quantity I < Quantity II
