b) 0.875

c) 0.525

d) 0.75

Radius of the circular plot = 56/2 = 28 m

Radius of the plot with the garden = 28 m + 7m = 35m

Area of the circular plot

Total cost borne by the farmer for building the entire garden

Let the number of boys invited on birthday = x

The number of girls invited on birthday = x + 2

According to question,

10x + 20(x + 2) = 280

10x = 20x + 40 = 280

30x = 280 â€“ 40

30x = 240

x = 240/ 30

x = 8

Let sales be Rs. (10000 + x)

Then, Executiveâ€™s Commission = 500 + 0.04x

According to question,

10000 + x â€“ 500 â€“ 0.04x = 31100

9500 + 0.96x = 31100

0.96x = 21600

Total sales = 10000 + 22500 = Rs.32500

n (M B) = n (M) + n (B) â€“ n (M B)

100 = 45 + 85 â€“ n (M Â B)

n (M Â B) = 130 â€“ 100 = 30%

Only n (B) = n (B) â€“ n (M Â B) = 85 â€“ 30 = 55%

Hence, 9.76 is the quantity alcohol remains.

Average of A = a = 10

b = 20

c = 30

Let na, nb and nc be the number of students is each classes given that

Average of B and C = 25

Let Purnenduâ€™s salary be Rs. 100.

After 25% increments, it will become Rs. 125% again, after 20% decrement, it will become Rs. 100. Now, taking Sanjayâ€™s salary to be Rs. 100

After 20% increments, it will become Rs. 120

After 25% decrement, new salary will become Rs. 90. So 100 R = 90 K

K/R = 100/90

Ratio if Sanjayâ€™s to Purnenduâ€™s salary is 10 : 9

Let the total number of voters be â€˜Xâ€™ then 4/5th of the votes.

Polled will be given to Satrughan Sinha, and rest i.e., 1/5th is been polled to Shekhar Again

10% of 4x/5th of the voters polled Satrughan Sinha

Now, Satrughan Sinha got 216 votes

18x/25 = 216

X = 25 Ã— 216 / 18 = 300

Shekar got 1x/5 of the total votes out of these voters only

80% voted, so shekar will get

80/ 100 Ã— (x/5) = 7x/25

Satrughan Sinha got 216 votes i.e. 18x/25 = 216

X = 300

300 voters were these allover out of which 10% for satrughan Sinha and20% for Shekar did not vote,

Votes polled = 300 = 3Ã—300/25 =264

Let the area of each face = A sq unit

So, total surface area = 6A

Hence, submerged area = 1/3 (6A) = 2A

So four vertical sides have A sq. unit under water, ie each vertical face has Â¼ of its height under water so volume of cube under water = Â¼ of volume

And volume of cube above the water = Â¾ of volume

Hence, required fraction = Â¾ = 0.75
