A sum of money became after interest 880 in 1 year and 1300 in 5 year . sum pf money is​

Answer 1

Answer:

880

Simple Interest SI=  

100

PNR

Also Amount A=P+SI

So, for four years,

2480−P=  

100

P×4×R

​

  -- (1)

And, for eight years,

4080−P=  

100

P×8×R

​

  -- (2)

Subtracting equation (1) from equation (2), we get

=>1600=  

100

4PR

​

 

=>PR=40,000

Substituting it in equation (1), we get

2480−P=  

100

4×40,000

​

 

=>P=Rs  880
