Please ask one query in a single post. The first question has been solved here. You can proceed the same way for the second one.
1. Principle amount P= 6250 Rs. 
Yearly interest rate is 8%. Hence, half yearly interest rate is R=4%. 
The amount is deposited for 1 year and , it's compunded half yearly. Hence, time period N=2 
Hence, the total amount after one year is given by 
P open parentheses 1 plus R over 100 close parentheses to the power of N equals 6250 open parentheses 1 plus 4 over 100 close parentheses squared equals 6760.
Hence, the compund interest obtained = total amount - principal amount = 6760 - 6250 = 510 Rs.
