Let x= side of the regular octagon. By symmetry, each figure cut from the corners must be an isosceles right(45-45-90) triangle,
and all four of them must be congruent. Then the leg of each isosceles triangle must have measure x/sqrt(2)
Then we must have x/sqrt(2)+x+x/sqrt(2)=2 or simplification,
x=2/(1+sqrt(2)) this is one side of octagon.
Area of octagon = 2(1+sqrt(2)) a^2, where a is side of octagon,
area of octagon = 2(1+1.414)(2/(1+sqrt(2)))^2 =3.31 cm^2

And then the 7th digit is x as given
then 7+a+b=18
a+b=18-7=11
a+b+x=18
11+x=18
x=18-11=7
Therefore, 7 is the value for x.

((256)^8)^32/7
256/7 remndr is 4
so again
(4^8)^32/7

65536/7 is giving the rmndr as 2
2^32/7
i.e (4^16)/7

using 10^100/7 rem= 4

similarly all terms will give rem= 4

1728*(100/100+8)=1600
At no discount...
sp=1920,cp=1600
diff between sp and cp is 320
the formula is (sp-cp/cp)*100=( 320/1600)*100=20%

for 1 lose
number of ways are =4!/3!=4

The 1st set has 10 terms and, 2nd has 20 and 3rd is 30.
The number of terms is AP. Find out the set in which 2269 occurs.
It is present in 21 st row, which will have 210 terms.
(21-1s, 42-2s, 63-3s, 84-4s)
at the end of 21 rows, total number of terms is 2310.
So from 2237-2310th term it will be 4.
So 2269th term will be 4

Sunny Sanyal to dhanaseelan 11 years ago

A hare and a tortoise have a race along a circle of 100 yards diameter. The tortoise goes in one direction and the hare in the other. The hare starts after the tortoise has covered 1/5 of its distance and that too leisurely. The hare and tortoise meet when the hare has covered only 1/8 of the distance. By what factor should the hare increase its speed so as to tie the race? a. 8
37.80
5
40

please help me with this question

dhanaseelan 11 years ago

Let the diameter D, speed of the Tortoise and Hare are S1, S2 respectively
Tortoise completed (1/5)th (i.e 8/40) of distance before Hare start.
when Hare starts race the remaining distance for Hare is D and for Tortoise is (32/40)D.
when they meet the distance travelled by the Hare is (5/40)D, and the distance travelled by the Hare is ((32-5)/40)
the time is equal.
so ((27D/40)/S1)=((5D/40)/S2)
S1/S2=27/5
now the remaining distance for Tortoise is (5/40)D, for hare (35/40)D
to tie up the race they have to cross the remaining distance in same time.
the new speed of the Hare is S3
so ((5D/40)/S1)=((53D/40)/S3)==> S3=S1*7==> S3=(S2*27/5)*7==>37.8*S2
So the Hare have to increase its speed by 37.80 times.
ans is 37.80

if there are three baskets full of fruits such as apples,oranges and mixture of both...and always the labelling of the basket is incorrect(i.e, if it is labelled as apples it need not be apples alone it might be a mixture)the task is to pick a single fruit from a basket...and correct the labels...

dhanaseelan 11 years ago

Take the fruit from the basket labeled mixture. Sure this basket is not mixture bcz labelled as mixture. So which fruit u r getting from the basket , is filled in the basket
for example if it is orange , that basket contains orange ly. label it as orange.
now consider the basket labeled apple, sure it ll not contain apple, so it must be mixture,another one basket is apple

Emanuel Abhishek Murmu 11 years ago

work done per month= 1/21
work destroyed per month= 1/28

for first 2 months,
work done = 1/21 - 1/28 = 1/84.

so, 1/84th work is done in months= 2
full work is done in months= 2/(1/84) = 2*84= 168 months

so, 1/84th work is done in months= 2

as they work alternate so wall will complete in 169 months.
