Directions (1-5):

Quantity I:

Area of the square = a2 = 324

Side of the square (a) = 18m

Length of the rectangle = 54m

Area of the rectangle = 54*44= 2376 Sq. m

Quantity II:

The perimeter of a rectangle = 212 m

2(l + b) = 212

l + b = 106 —> (1)

l โ b = 18 —> (2)

By solving the equation (1) and (2), we get,

Length = 62 m, Breadth = 44 m

Area of the rectangle = 62*44 = 2728 Sq. m

Quantity I < Quantity II

Quantity I:

Downstream speed= 64/8 = 8 km/hr

Upstream speed= 8*(3/4) = 6 km/hr

Speed of boat in still water = ยฝ *(8+6) = 7 km/hr

Quantity II:

Downstream speed= 72/8= 9 km/hr

Downstream speed = Speed of boat in still water + speed of stream

Let the speed of boat be x

=> x + 3 = 9

=> x= 6 km/hr

Speed of boat in still water = 6 km/hr

Quantity I > Quantity II

Quantity I:

T= D/S

T = (250 + 200)/[(40 + 60)*5/18]

T = 450/(100*(5/18)) = 16.2 sec

Quantity II:

T = D/S

T = (170 + 180)/[(80 – 60)*(5/18)]

T = 350/(20*(5/18))

T = 63 sec

Quantity I < Quantity II

Quantity I:

Present age of Anitha = 15 + Present age of Rahul

After 10 years, The ratio of ages of Rahul and Anitha = 7 : 10(7x, 10x)

10x โ 10 = 15 + 7x โ 10

10x โ 10 = 7x + 5

3x = 15

X = 5

The age of Anitha, after 4 years = 10x โ 6 = 50 โ 6 = 44 years

Quantity II:

The ratio of present age of Naveen and Priyanka = 3 : 1

The ratio of present age of Gourav and Priyanka = 5 : 3

The present age of Naveen, Priyanka and Gourav = 9 : 3 : 5

The age of Gourav, after 6 years = 21 years

The present age of Gourav = 15 years

5โs = 15

1โs = 3

Required sum = 17*3 = 51 years

Quantity I < Quantity II

Percentage of interest received from these schemes

= 5340*100/35600

= 15%

By the rule of allegation,

= > 1 : 1

2โs = 35600

1โs = 17800

Quantity I:

Sum of money invested in scheme A= Rs. 17800

Quantity II:

Sum of money invested in scheme B = Rs. 17800

Quantity I = Quantity II
