What sum would yeild an interes
of $80 in 4 years at 4% pa?

​

Answer 1

Answer:

For first 4 years

SI=PTR/100

=(800X4X8)/100

=256

For last 4 years

SI=(800X4X6)/100

=192

on adding 256+192=RS.448

FOR 8 years it is 448(missing the middle 5th year as it has not given any values in the question)

by taking mean of(6+8)/2=7

SI for 5th year = (800x1x7)/100=56

adding it to 448+56=504

or simply we can solve taking mean for all the years

SI=(800X9X7)/100=504

However we calculate answer is the same
