Answer 1

Answer:

Principal amount =8000/-, R/interest = 10%

Step-by-step explanation:

i) First year interest = Principal amount × R/interest × 1 year ÷ 100

》8000×10×1÷100= 800/-

ii) second year principal = principal amount + first year interest

8000 + 800= 8800/-

iii) second year interest = second year principal + R/interest ÷ 100

》 8800 + 10 ÷ 100 = 880/-

iv) second year final amount = second year principal + second year interest

》 8800 + 880 = 9680/-

v) 2 year earned interest = 2 year final amount - principal amount

》 9680 - 8000 = 1680 /-
