Suppose total number of trees = X;
His mother gifted 1 tree for every birthday till 8 years.
Also the ration between trees always should be whole number.....okay lets see the relation..
(x-1)/1 = whole number,
(x-2)/2 = whole number,
(x-3)/3 = whole number,
(x-4)/4 = whole number,
(x-5)/5 = whole number,
(x-6)/6 = whole number,
(x-7)/7 = whole number,
(x-8)/8 = whole number

Now we have to find the LCM of (1,2,3,4,5,6,7,8) which is = 840.

Now cross check with each iteration..means
(840-1)/1 = whole number,
(840-2)/2 = whole number,
(840-3)/3 = whole number,
(840-4)/4 = whole number,
(840-5)/5 = whole number,
(840-6)/6 = whole number,
(840-7)/7 = whole number,
(840-8)/8 = whole number,

So, the answer will be .... 840
