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.

Consider the initial rate of interest be 10%, then the principle is calculated to be 2000. Using 12% rate of interest the new SI is 2100. So the answer is Rs. 350.

It's not 35,
Here its written, the rate increased 2% more means, new rate= (R+2) not (102R/100) ,
So, the answer cannot be found unless we have the principal.

s.i = p * 7 * r/100 = 1750.
If rate of interest increses by 2% then p * 7 * 1.02r/100 = 1750 * 1.02 = 1785.
The extra interest he will get = 1785 - 1750 = 35.

1750 = P * 7 * R/100.
So P * R = 25000.
If R is 2% more then P * R * 102/100 = 25500.
So new S.I.= 25500 * 7/100 = 1785
so increase S.I = 1785 - 1750 = 35.
So P * R = 25000.
If R is 2% more then P * R * 102/100 = 25500.
So new S.I.= 25500 * 7/100 = 1785
so increase S.I = 1785 - 1750 = 35.

GIven that: (P*R*7)/100 = 1750
Now we have to find : P*(R+2)*7/100 = ?
But we cannot find P and R both from just one equation.
Hence Cannot be determined

As SI is directly proportional to R..
so if r is increased by 2 %
SI will also increase by 2 %
so ans is 35(2% of 1750)
let me kno if i m wrong.. :)

ANS : 245.
Interest is increased by 2% more,so (7 years) x 2% = 14%.
Interest is 1750, so now 1750 + 14% = 1995.
The difference between 1995-1750 = 245.

I think 245 is correct as they asked for Increase in interest. So 2% of total interest earned for 7 year is 245. Please clarify me if it is wrong one.

Ans: B.
In the 1st case: S.I = 245R/2 (Let, R =Rate of Interest).
In the 2nd case: S.I = (245R/2+490/2).
So, in the 2nd case we have Rs.245 extra.

The Answer is 35.
Equation One = 7*P*R/100=1750
to be found (7*P*R+2)/100 = ?
we can rewrite as (7*P*R)100 + 2/100 = ?
and then 1750 + 2/100 = 35.
