A certain amount earns simple interest of Rs. 1750 after 7 years. Had the interest been 2% more, how much more interest would it have earned?
Answer: Option
Explanation:
We need to know the S.I., principal and time to find the rate.
Since the principal is not given, so data is inadequate.

pr = 1750/7 = 250
r = 250/p.
2% more => 250/p + [250/p]*2%=255/p is the new r.
SI = p * 255/p * 7 = 1785.
1785 - 1750 = 35 rupees more.
r = 250/p.
2% more => 250/p + [250/p]*2%=255/p is the new r.
SI = p * 255/p * 7 = 1785.
1785 - 1750 = 35 rupees more.

As per data specified p and yr are constant only rates changes.
Moreover, SI is directly proportional.
So, I think the answer would be 35.

Hi @Anusha,
As in question given, 2% more interest than the first case,
So, rate of interest = r+(2r/100) = 102r/100.
Hope understood.

How we solve it?
Find the rate %per annum by applying the formula: r = I * 100/t * p.
Rs. 700 gives Rs 210 simple interest in 3 years.

Rs. 700 gives Rs 210 simple interest in 3 years.

Please anyone confirm that what is the correct answer or data is not sufficient. As Indiabix says answer "Cannot be determined".

The answer cannot be determined because the principal is not given and we cannot assume rate r to be 100 or any value. Thanks.

S.I. for 1 year = 1750/7=250.
increase by 2% = 250*2/100=255.
Every yr he would get extra 5 rs.
So, for 7 yrs = 5 * 7= 35
increase by 2% = 250*2/100=255.
Every yr he would get extra 5 rs.
So, for 7 yrs = 5 * 7= 35

I think 35 is right answer.
1750/7=250 is S.I. Per year.
2% more of 250=255.
Therefore 5 is more.
5*7=35 is right.
1750/7=250 is S.I. Per year.
2% more of 250=255.
Therefore 5 is more.
5*7=35 is right.

Hey friends it was said that when no principal amount given then take 100 =p so why we can't write this value.
