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.

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?

"Had the interest been 2% more, " - S.I is increased by 2% right? not the Rate of Interest (R).

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.

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.

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.

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.

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.

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].

1750 divided by 7 give Interest for one year ie, Rs 250.
Here, 2% of 250 is 5.
So if the interest is increased by 2% then the Interest for one year will 255.
So for 7 years 1785.
Thus the difference will be Rs 35.

B is correct.
2% for 7 years will be 14%.
14% of 1750 is 245.
2% for 7 years will be 14%.
14% of 1750 is 245.
