Answer / neelam venkata balaji

let's number is n
so n=Dx+8------->1
n=3Dy+21--------->2
from 1 & 2 D(x-3y)=13
here 13 is prime number so it has factors 1 and 13 only
x-3y must be 1
let x=4 and y=1
then n=60
so 2n is divided that is 120 by 3D that is by 39 we get
the remainder as 3

Answer / sourabh

let's number is n
so n=Dx+8------->1
n=3Dy+21--------->2
from 1 & 2 D(x-3y)=13
here 13 is prime number so it has factors 1 and 13 only
x-3y must be 1
let x=4 and y=1 BUT THESE NUMBER DONT SATISFY EQ 1 AND 2 IE
IF WE PUT X=4 IN 1 WE GET N=50 AND IF WE PUT Y = 1 IN 2 WE
GET N=60
SO WE LET X=7 AND Y = 2
then n=99
so 2n is divided that is 198 by 3D that is by 39 we get
the remainder as 3

Answer / avinash kulkarni

number be n
i.e divided by D i.e= n/D=8;
divided by 3D is n/3D=21;
question is n/3d=21 i.e 21/3D
so, 21/3*1/D
7*1/D=7/D
there is not at all possible to divide 7.. if so, we will get an ans in decimals
so, ANS IS....
Cannot be determined

Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be
