Problem on simple and compound Interest

Hello, Can some one help me in solving this problem.

Ravi invests a two equal amounts in two different schemes run by a bank. After 2 years, he gets Rs.700 as the simple interest in the first scheme, while in the second scheme he gets Rs.749 as the compound interest. What is the total amount he invested in both the schemes?

Note: The solution for this problem is given based on the concept: Compound Interest for 2 years - Simple Interest for 2 years = Interest earned on Simple Interest of 1st year during the course of second year.

Is there any other way to solve this problem?

Thanks in advance.

By formula

By formula SI=ptr/100 4900=p1r Let the intial be P then 35000=Pr P / p1 =350/49 =50/7 p1 =pr/100 => P / p1 =100/r 50/7 = 100/r =>r = 14 and P = 35000/14 = 5000/2 = 2500 Hope u can follow it. Just Now I am leaving for the day, once I reach home I ll explain in details

This is a very easy question

This is a very easy question if you do the proper analysis First the simple interest is given as 700. We know simply interest remains same for all the year so SI for 1st year is 350. Now the compound interest is same as SI for 1st year. So the CI for 1st year is 350 and thus for second year is 350+49 So 49 is the amount you get from the SI of 350 Thus 49= 350*r/100 where r is the rate of interest =>r = 4900/350 = 70/5= 14 And now SI for first year is 350 so 350=p*14/100 where P = Initial principle amount =>p = 35 000/14 = 2500 So he has invested 2500 on both the schemes. and total amount = 2*2500 = 5000
