It's more than 3600, so its greater than 60.
it's less than 4900, so its less than 70.
a no.'s root can end with six if the no. ends with 4 or 6.
so the no is either 64 or 66.
Now if it's 66, the square must be greater than sq of 65.
65 sq= 4225
the given no. is greater than sq of 65.
Therefore the number is 66.
Equal to 3n+p
i think thats it
That is 3 slots
12 in 1st slot
11 in 2nd
10 in 3rd
so that is 12*11*10 or 1320 ways
X = 13, Y = 10
I'm a bit tired right now, so I'm not going to explain my work, but hopefully this still helps.
Good luck with your schoolwork/homework!
