Answer:
YTM = 5.35%
YTC = 5.44%
Explanation:
the YTM = {coupon +[(face value - market value)/n]} / [(face value + market value)/2]
YTM = {67.5 +[(1,000 - 1,150)/15]} / [(1,000 + 1,150)/2] = 57.5 / 1,075 = 5.35%
the YTC = {coupon +[(face value - call value)/n]} / [(face value + call value)/2]
YTC = {67.5 +[(1,000 - 1,067.5)/6]} / [(1,000 + 1,067.5)/2] = 56.25 / 1,033.75 = 5.44%
