I got m as 202 ;
consider 1st sequence of consecutive numbers as a , ..... , a+m
2nd sequence a' , ..... ,a'+2m
as difference between maximums is 99
a'+2m - a-m =99 ;----- (1)
sum of n terms in ap = (n/2)*;
by applying for both the sequences
2a+m=4;---- (2)
2a'+2m=1...

1/3 *(pi)*r^2 * h = 2/3 *(pi)*r^3 = 718 2/3
Base of cone covers one side of cube, h = 2r
So, radius will come out to be 7
Cube : 14x14x14
Cone : radius = 7, height = 14
Now, calculate...

Madan is going from Mumbai to Delhi in order to join a new job there. He has a glass memento of right
circular conic shape under his possession and he does not want it to break during transportation. So,
he purchases a cubic metal box from the market spending Rs. 500. The cone is exactly fi...

Now, OPQ = S, So, OPM = 2S
AO:OM = 2:1
So, APO = 4S
So, AMP = 6S
And hence, AMC = 12S
And, ABC = 24S

a + b + c + d + e = 12(edit)
where a and e can be 0, but b,c,d can be minimum '1'
Ways = C(13,4) = 715
Total ways = C(16,12)
Probability of no adjacent = 715/C(16,12) = 11/28
Probability she can park = 1-11/28 = 17/28

Without pen/paper, don't mind if wrong...
(5x)^2 = (3x+r)^2 + (2x+r)^2
Or, 12x^2 = 10xr + 2r^2
Or, 6x^2 - 5xr - r^2 = 0
Or, x = r, -r/6
So, 10x+2r = 36
Or, r = 3

A right angled triangle ABC is right angled at B. The point of contact of the incircle with the hypotenuse, divides it, in the ratio 3:2. If the perimeter of the triangle is 36 cm, find the inradius.

i dont have the oa , but i think first case me aisa nahi hona chahiye = 1 blue , 0 red in bag 1..and 9 blue, 5 red in bag 2 ??
aur second wale me bhi 1 red , 0 blue in bag 1 .... and 4 red , 10 blue in bag 2
i think these would give better probablilty as per conditions . ??
