My answer: 58.

There is shorter way:

rearranging the given equation i get:

x = (y+1)/4 + 4y

Now we are looking for integer values of x,

Therefore, (y+1)/4 must be an integer.

At x=1000, y=235.2

So what i am looking for is number of multiples of 4 between 0 & 235.

(Because 1 less than mutilple of 4 will make (y+1)/4 integer)

Now u can calculate that there are 58 mutiples of 4 between 0 & 235.

Thus answer: 58

does my answer matches official ans.

Great Approach! Getting y be itself is a big leap towards the solution.

Just a bit off..but thats enough to get it wrong unfortunately.

The official answer is 59.

Heres what i found out:

you are looking for y+1 /4

So you are looking for multiples of between 0 and 23

6.2

Thats 59.

Thanks for the solution
