Interpretation – Futures

Dear Tutor,

Can you help please?

QUESTION

TODAY
LIBOR 6.5%
Futures 93.20

On the date of Investment, what will be the hedge result using futures if:
a) Interest rates fall by 1% – Futures prices move by 0.85%
b) Interest rates rise by 2% – Futures prices move by 1.9%

Solution A
LIBOR will now be 5.5%
Futures will be (93.20 + 0.85%) = 94.05

Solution B
LIBOR will now be 8.5%
Futures will be (93.20 – 1.90%) = 91.30

MY UNDERSTANDING (i.e. My Solution)
The question said futures moved by % (percentage), hence not an absolute figure as used in the solution above. So I had:

Solution A
LIBOR will now be 5.5%
Futures will be (93.20 + 0.85% x 93.2) = 93.99

Solution B
LIBOR will now be 8.5%
Futures will be (93.20 – 1.90% x 93.2) = 91.43

Is my interpretation of the % correct? And if so, should i just state my assumption/interpretation in the exam and I get my marks?

Thanks
