Q57 asteroid

since asteriod is receiving money from swiss its reverse money market

euro [ pv ]……………………………………………. [ fv ]
deposit <———————————- 1.5 euros
. { x * 2/12}
;
\ / { * 1.6199}
borrow X {1+2.17} X
(CHF)

Shouldn’t flow be like this (money market hedge )
here borrowing rate of chf is directly given 2.17 then why we are finding out i(c) in forward rate calculation
we need to find i(b) right since deposit rate of euro is not given?? and why we are multiplying rates by 2/12 when its already 2month interest rate.Hope my chart flow is understandable
