Back in 1985, When the Deutsche Mark Still Existed, the Yield

Back in 1985, when the Deutsche mark still existed, the yield curves were as follows:
$\begin{array}{cccccc}&\text { U.S.}& \text {Deutsche}&\text { Japanese}& \text {Swiss}& \text {British }\\\text { Maturity } & \text { Dollar } & \text { Mark } & \text { Yen } &\text { Franc }& \text { Pound }\\ \hline 12 \text { months } & 8.31 & 4.81 & 7.19 & 4.31 & 11.31 \\5 \text { years } & 9.78 & 6.40 & 6.82 & 5.40 & 10.90 \\7 \text { years } & 10.16 & 6.75 & 7.00 & 5.45 & 11.00 \\10 \text { years } & 10.33 & 6.80 & 7.33 & 5.70 & 11.14 \\\text { Spot Exchange } & & & & \\\text { Rate (per US\$) } & & 2.50 & 200.00 & 2.10 & 0.70\end{array}$ Calculate the implied forward exchange rates, assuming that yields on zero-coupon bonds (European convention) for maturities of more than one year.
