Question

3. On what sum
of money (principal )does the
S. I for 10 years at 5%
become Rs 1,600 ​

Answer 1

Step-by-step explanation:

Let the sum of money be x.

Rate of interest=5%

Time=10 years

So simple interest for 10 years on the sum of money x at 5% per annum will be,

5*10*x/100= x/2

Now, sum of money+simple interest=1600

So, x+x/2=1600

Or, 3x=3200

Or, x=3200/3

Answer 2

Answer:

given, t = 10 years, r = 10%, SI = 1,600

to find P = ?

SI = PTR/100

P = 100*SI/T*R

P = (100*1600)/(10*5)

P = Rs 3,200
