503/2=251.5
31/2=15.5
251.5-15.5=HARMONY
251.5+15.5=MAGLEV
HARMONY=236
MAGLEV=267
According to info given, the two added up should equal 503 and the maglev is faster than the harmony by 31, so subtracting 236 from 267 should equal 31
267-236=31
267+236=503
The other person posted an incorrect answer as the sum is not 503 in his.
