Answer & Explanation

1. 2

Area of the square = 196 sq cm

Area of the four quadrants = Area of the circle with radius

= 7 cm

= 22/7 × 72 = 154 sq. cm.

Required Area = 196 – 154 = 42 sq. cm.

1. 1

Let the length be l so breadth = l/2

Now, l × l/2 = 10000/50

l^2 = 400

l = 20

Now, 2lh + 2 × l/2 × h = 129600/480

3lh = 27

h = 270/(3*20)

h = 4.5 m.

1. 3

Let h be the height up to the level of water in the cylinder.

Volume of water in the cylinder = 22/7 r^2 h = 22/7 * 144 * h

Let h1 be the height to which the water level is raised.

22/7 * 144 * (h1 – h) = 4/3 * 22/7 * 216

h1 – h = 2cm

1. 2

Distance in 60 minutes = 33000 meters

In 1 min distance = 33000/60 = 550 m

Hence, number of revolutions per minute = 550/(2*22/7*0.35) = 250

1. 5

Probability that the house could be raided on any day in 5–

day period = 1/2 * 1/2 * 1/2 * 1/2 * 1/2 = 1/32

Required probability = 5C3 * 1/32 = 10/32 = 5/16

1. 5

The probability of any one winning the race given that

dead heat is possible is

P (A wins, B loses and C loses) + P (B wins, A loses and C loses) + P (C wins, B loses and A loses), i.e.,

1/12 * 4/5 * 11/13 * 1/5 * 11/12 11/13 * 2/13 * 11/12 * 4/5

= 11/195 + 121/780 + 22/195

= 33/195 + 121/780

= 253/780

1. 2; Let the no. of articles be 100

Let the C.P of 1 article = Rs. 1

Total C. P = Rs. 100

Total selling price = 40×1.5 + 30 ×6/7 + 30×0.75 = 108 3/14

%Profit = 108 3/14 – 100 = 8 3/14%

1. 1

When difference in SP is Rs. 14.5 then C.P is Rs. 100

if difference in S.P is Rs. 35 then C.P = 100/14.5 * 35 = Rs. 241 11/29

1. 3; C.I – S.I = Rs. 1253.6589

1253.6589/23700 * 100 = 5.2897 % of the sum

We know that 13% is the required rate of interest because in 3 yrs, CI became 44.2897% of the sum and SI remains 39% of the sum, the difference is 5.2897%.

So option 3 is correct.

1. 1

Amount of wine left = 40 * 9/10 * 9/10 * 9/10 * 9/10 * 9/10 = 23.61 litres

Water = 40 – 23.61 = 16.38

Approximate ratio = 24 : 16 = 3 :2
