Step-by-step explanation:

1) Compounded Annually :

P=Rs.80000

R=10% p.a.

T=1  1/2 years ⟹n = 1+  1/2

Amount for 1st year.

A=P[ 1+ R/100]^n

=Rs.80000 [1+  10/100] = =Rs.88000

SI on Rs. 88000 for next 1/2 year  

=Rs.88000 *   10/100 * 1/2 =Rs.4400

Therefore, Amount = Rs.88000+Rs.4400 = 92400Rs.

2) Compounded half yearly :

P=Rs.80000

R=10% p.a.=5% per half year

T=1  1/2 years ⟹n=3

A=Rs.80000[1+ 5/100]^3

A=Rs.92610

Thus, the difference between the two amounts

= Rs.92610−Rs.92400

=Rs.210
