So in the interval of three years the sum ended up becoming 1350 from 1260.
Total increase is equal to 90 in 3 years. So in one year the increase is of 30 Rs.
And as per the question the sum became 1260 in two years. It means it must have increased by 30+30 = 60 before it became 1260. So the initial sum was 1200 which became 1230 in the end of the first year and 1260 in the end of the second year. The sum increasing by 30 every year. And 30 is what percent of 1200. It is 2.5 % which is your rate of Interest too.
