Hello All,
Due to software issues in the NL which will take time to get fixed, we are suspending QQAD for few days. My guess is that we will be ready in next 5 days.
If possible we will run contests on this thread in the coming days -> some fun types, the announcement of which I will make by evening today.

(1) 1 (2) 3 (3) 5 (4) 7 (5) none of these | assume x = y (=40).
now the values of 'x' n thus 'y' can be 4*(sqrt5) or 3*(sqrt5) or 2*(sqrt5)
if it goes more than 4sqrt5 thn the other value becomes -ve thus does not exist.
thus there r 5 values.
ans is option '3'

(1) 1 (2) 3 (3) 5 (4) 7 (5) none of these | My answer - (2) 3 x=y=80 x=180 , y= 45 x=45, y =180
let 1/ rt(20) = k
k = k/2 + k/2
or = k/3 + 2k/3
cannot go further as 1/ rt(20) is 1/ 2*rt(5)
so if i take k/4 + 3k/4 i will not able to maange this 3 here and same is for higher terms.
This sol. is considering x and y as integers.
Otherwise there are infinite solutions
