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 236
Thanks for the solution
