The difference between the interests earned on a principal under a certain rate of compound interest in pth year and (p + 1)th year is more than that in the qth year and (q + 1)th year if
p > q
p = q
can't say
p<q
Because compound interest Is depend on the number of years, so if the interest in Pth year and (p+1) th years is greater than Qth years and (Q+1) th year if and only if P > q
