Question

3. The amount of 28,000 at 5% per annum com-
pound interest in 2 years will be-​

Answer 1

Answer:

Compound Interest

formula :- P×(1+R/100)²

28000×(1+5/100)²

5 and 100 cancel

it will Be 20

so

28000×(21/20)²

28000×21/20×21/20

28000×441/200

Two Zeros 00 cancel

it will Be 280×441/2

=280÷2=140

140×441=61,740.

CI=61,740

Amount = CI- Principal

61,740-28000=33,740.
