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.

According to me, the question says to increase the rate by 2%. Which means if the original is R% then the new rate is (R+2)%.
So old interest.
I=PR*7/100.
And new interest.
I'=P*(R+2)*7/100.
Thus the answer can't be determined without the principal.

Here the answer is 35.
Because 2% is not the increasing percentage of rate of interest it is only the increase in the total interest which is given below.
So, the 2% of 1750 is 35.

So, the 2% of 1750 is 35.

No, @Jaimunis.
1750/7=250 is the correct answer.
1750/7=250 is the correct answer.

Let Principal=100 so,
1st interest = prt/100,
=> 1750= (100 * r * 7)/100,
=> r = 250,
Then if r increases by 2%,
then r =250*102/100 = 255,
so 2nd interest = (100 * 255 * 7)/100 = 1785,
Difference = 1785 - 1750 = 35. (ans).

According to me;
Interest for 7 yr is 1750 means
For 1 yr interest is 250.
So assume the interest is 10% this way principle amount becomes 2500.
And now 8% interest for 7 yr of 2500 = 1400.
So the more interest earned = (1750-1400) = 350 ans.

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
