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.

Can we consider the amount as 1000 and calculate the interest. As for one year S.I is 250. So we get the rate of interest as 25. And if we add two percent to it and get S.I it will be 270. 270x7 will give you 1890. So 1890-1750 should give you 140. Then Why it can't be determined?

The answer should be 35.
Given:
p*r*7/100 = 1750.
According to question;
new rate = r+2%of r.
new rate = r+0.02*r.
new rate = 1.02*r.
Hence new SI = p*1.02*r*7/100,
new Si = 1.02*p*r*7/100,
new Si = 1.02*1750,
= 1785.
Difference = 1785-1750 = 35.

SI=P * R/100 * T,
1750=P * R/100 * T,
When R increase by 2%.
R become 1.02R,
new SI = P * 1.02R/100 * 7,
= P * R/100 * 7 * 1.02,
= 1750 * 1.02,
= 1785.
Increase in SI = 1785-1750 = 35.
1750=P * R/100 * T,
When R increase by 2%.
R become 1.02R,
new SI = P * 1.02R/100 * 7,
= P * R/100 * 7 * 1.02,
= 1750 * 1.02,
= 1785.
Increase in SI = 1785-1750 = 35.

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
