Answer 1

Answer:

21 yrs

Step-by-step explanation:

Given P=1288 Rs

after 7 yrs Amount=2576 Rs

Interest for 7 yrs=2576-1288

=1288 Rs

Interest for one year=1288/7

=184 Rs

Interest calculated from the Principal 1288

to an amount of 5152

= 5152-1288

=3864 Rs

There for the period taken = 3864/184

=21 yrs
