Answer:
Yield to maturity =11.75%
Explanation:
The yield to maturity to Maturity van be worked out using the formula below:
YM =( C + F-P/n)  ÷  ( 1/2× (F+P))
C- annual coupon,
F- face value ,
P- current price,
n- number of years to maturity
YM - Yield to maturity
C- 8%× 1000 = 80, P- 878.31, F- 1000
AYM =  80 + (1000-878.31)/4  ÷  1/2×  (1000+878.31)
    = 110.4225   ÷ 939.155

Yield to maturity =11.75%
