(9+9)/40+42+9+9)x100%=18% recombination between Height and Snout genes. The other data from number 4 are 5% between Antennae and Snout and 12% between Height and Antennae. These can be reconciled by having Height-12 cM-Antennae-5cM-Snout.

Work Step by Step

The key here is to remember that a cM is 1% recombination between two loci. Play with different physical arrangement until you find one which approximately matches all of the data.
