So in One and half years the amount increase by 378. So in 3 years it will be = 378×2. So in year it will be = (378×2)/3 = 126×2 = 252
as per question, the sum became 4734 in 4.5 years. And every year it increase by 252. So in 4.5 years, it increased by 1134 before it became 4734. This means it must have been 4734 - 1134 = 3600 before it could become 4734.
so the amount was 3600. answer
Let's now find the rate. Since it increase by 252 every year. So let's find what percent is 252 of 3600.
(252/3600)×100
= 7 % Answer.
