let p&q be 2 +ve integers such that p - q = 75 & the LCM of p & q is 360.Find the value of p+q?

Answer 1

i believe q is 45 and p is 120. To find this answer i cheated a bit. I went in microsoft excel and in the left most colum made a series series starting from one and going till the end of the page. Then in the colum next to that, gave the following formula:

=mod(360,A1)+mod(360,B1)

Then i copied the formula to the end of the list. And found that when q equals 45, the total mod of q and p is 0. therefore q is 45 and p is 45 + 75 = 120
