An easy one:

India vs Pakistan match...current score: India 214/3 ( Sehwag - 18, Yuvi -09)
So in how many ways did the previous 3 batsmen score, assuming:
1.) any of the 3 cud've got a zero
2.) No one got a zero
Consider zero extras in both cases.

PS: Sachin out on 99 yet again(

PS: Sachin out on 99 yet again(

no. of runs scored by 3 batsmen=214-27=187
x1+x2+x3=187
no. of ways=187+3-1C3-1=189C2
2)no one gets zero=186C2
ignoring sachin score of 99

0.wxyz.........=wxyz/9999=wxyz/3*3*11*101
now DED can be either 101, 303 or 909
but since the no. is less than 1 hence it should be 909
also numerator should be divisible by 11 to make denominator 9999
check for 11^2=121 , 242,363 ,484
we get numerator 484
hence 484/909

we cannot get a single value because the circle can intersect in many different ways
