Simple Interest = ( 8000 x 8 x 9 ) / ( 100 x 2 ) = Rs. 2880 
Amount = Rs. 8000 + Rs. 2880

Answer 2

Hey,sup!

As per the question,

Principal= 8000Rs.
Rate = 8%.
Time=4 1/2years = 4.5 years
Amount= ?.
Amount= principal+ simple interest.
Amount=principal+(principal×rate×time)/100
= Principal (1+rate×time/100).
=8000(1+8×45/100×10).
=8000(1+360/1000).
=8000(1+36/100).
=8000×136/100.
= 80× 136.
=10880Rs.

Hope it helps.
