Interest Rate Risk

Bond J has a coupon rate of 4 percent. Bond K has a coupon rate of 14 percent.

Both bonds have 17 years to maturity, a par value of $1,000, and a YTM of 8 percent, and both make semiannual payments.

If interest rates suddenly rise by 2 percent, what is the percentage price change of these bonds?

What if rates suddenly fall by 2 percent instead?

What does this problem tell you about the interest rate risk of lower-coupon bonds?

I need excel solution for these questions.
