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.

You're right @Depresser.
In the question earlier interest was let it be R%, later part of the question if interest is increased by 2% that means " R+0.02 " not [ R+R * 0.02].

The answer is Rs. 35.
Because the 2% more is on Simple Interest and not on the interest rate. Therefore we can directly find 2% of given simple interest in one year and multiply by 7.

1750 = PR7/100.
=>PR = 25000-----(1).
Again,
SI = (P*102/100*R*7) / 100.
=>PR = (100*100*SI) / 7*102------(2).
By equating (1) and (2).
SI = 1785.
So ans is 1785-1750 = 35.
=>PR = 25000-----(1).

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.

2% increase in interest- here interest is simple interest because we never call rate of interest as interest.
So answer is 2% of interest= (2% of 1750) =35 given, interest=1750.
So answer is 2% of interest= (2% of 1750) =35 given, interest=1750.

Here the ans is sp=3500
prinicipal amount is same so p1=p2=x,time is same,the rate is different r,2r
p1=p2
sp1*100/t1r2=sp2*100/t2r2
1750/(7*r)=sp/(7*2r)
sp=3500
so sp2-sp1=1750
prinicipal amount is same so p1=p2=x,time is same,the rate is different r,2r
p1=p2
sp1*100/t1r2=sp2*100/t2r2
1750/(7*r)=sp/(7*2r)
sp=3500
so sp2-sp1=1750

We have 1750 as interest.
Let say this is our 100% interest so, we have to find 102% interest .
That's it just cross multiply .
100=1750.
102=?
(1750 * 102)/100 = 35 rs.

As rate of interest is 2% for 7 years it is 14%.
That's why there is increase in interest that is 1750(14%increase) = 1995.
The extra amount would be 1995-1750 = 245.

Question is "how much more interest would it have earned?". So we already have simple interest of Rs. 1750.
So, 2% of 1750 will be 35.
Please correct if I'm wrong.

All the solution are based on the percentage of a ate of interest. But if you don't know the actual amount how could you say that the 2% of this amount will be this?
