If N ÷ 5 leaves remainder 3 and N ÷ 2 leaves remainder 0, then N ÷ 10 leaves remainder 4.
False(F)
Here it’s given N ÷ 5 leaves remainder 3
⇒ N = 5n + 3,where n = 0,1,2,3,..
and N ÷ 2 leaves remainder 0
⇒ N is an even number
But N = 5n + 3,it’s sum of two terms whose second term is odd.
Therefore,5n should be an odd number.
5n can be odd when n = 1,3,5,…
So, in this case when N = 5n + 3
⇒ N = 5(1) + 3 = 8 when(n = 1)
Hence when we substitute n = 1,3,5,.. in N = 5n + 3,we get 8,18,28 etc
Now, when we divide N by 10 ,N can be written as
N = 10×n + 8,when n = 0,1,2,3,..
Therefore, when N ÷ 10 ,always leaves remainder 8.
