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 

Hence, the compund interest obtained = total amount - principal amount = 6760 - 6250 = 510 Rs.
