15500-12500 = 3000.

100 * 3000 = 30000.

12500 * 4 = 50000.

100*30000/12500 * 4 = 6.

100 * 3000 = 30000.

12500 * 4 = 50000.

100*30000/12500 * 4 = 6.

You can solve by percentage method;

Simple interest is 3000 for 4years,

So 3000/12500x100% = 24%,

24/4 = 6,

Ans is 6.

15500 - 12500 = 3000.

100% = 12500,

= 3000.

=> 24% for 4 years ,

Then 1 year = 6%.

100% = 12500,

= 3000.

=> 24% for 4 years ,

Then 1 year = 6%.

Amount = Principal+S.I.

=>S.I. = Amount - Principle.

=>S.I.= 15500-12500 = 3000 (S.I. for 4 years).

As S.I. is same in every year,So 1st yr=750.

12500*X/100 = 750.

=>X=750/125= 6%.

=>S.I. = Amount - Principle.

=>S.I.= 15500-12500 = 3000 (S.I. for 4 years).

As S.I. is same in every year,So 1st yr=750.

12500*X/100 = 750.

=>X=750/125= 6%.

I = Pin

where I = is the amount of interest

P = present amount

i = rate of interest

n = number of years

If Future Amount is 15500 and

Present amount is 12500. Therefore 3000 is the amount of interest.

F = P + I.

Then;

I = Pin/

3000 = 12500 * 4 years.

i = 0.06 *100.

= 6%.

where I = is the amount of interest

P = present amount

i = rate of interest

n = number of years

If Future Amount is 15500 and

Present amount is 12500. Therefore 3000 is the amount of interest.

F = P + I.

Then;

I = Pin/

3000 = 12500 * 4 years.

i = 0.06 *100.

= 6%.

Here, it is taken 12500 and returns 15500, that means the total amount of interest given is 15500 - 12500 = 3000.

Principal amount = 12,500.

Period = 4 Years.

Rate = Find.

So,

S.I = (15,500-12500) = 3000.

Rate ={100 x 3000/12,500/4} = 6%.

Period = 4 Years.

Rate = Find.

So,

S.I = (15,500-12500) = 3000.

Rate ={100 x 3000/12,500/4} = 6%.

Let me explain guys

12500 is the actual amount after 4 years amount will be 15,500 with simple interest alright so that we need to find what per cent of interest they paid for 12,500.

15,500-12500

3000.

SI = PTR/100.

Si = 100*r/p*t.

100*3000/12500*4,

6%.

Simple To get per year S.I.

15500 -12500 = 750,

Then keep anyone sum as 100%.

100% = 12500,

Then,

X = 750 *100/12500.

X = 6.

15500 -12500 = 750,

Then keep anyone sum as 100%.

100% = 12500,

Then,

X = 750 *100/12500.

X = 6.

Amount Rs.15,500.

The sum Rs.15,500.

Amount = 15,500 it means S.I is 3000 (i.e S.I = Amount - Sum = 15,500 - 12,500=3,000)

3000 is 24% of 12,500 (because 12,500 // 1% = 125 // 3,000/125=24% ).

But 24% is for 4 year.

So we divide 24%/4 and got rate 6% p.a.
