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.

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

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.. :)

@ALL
SI = (PRT/100)
By applying given data in the above formula
1750 = (P x R x 7/100)
In order to find rate 'R', we need the value of 'P' (Principal amount).
Since the principal is not given, so data is inadequate.

How we solve it?
Find the rate %per annum by applying the formula: r = I * 100/t * p.
Rs. 700 gives Rs 210 simple interest in 3 years.

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].

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.

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.

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.

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.
