Tricky math

3 ppl go stay hotel


tauke say rm300

so each ppl pay rm100

then tauke give discount

room rm250 only

tauke ask bell boy give them back rm50

bell boy take rm20 masuk pocket

so they 3 ppl get rm30

so each ppl get rm10

mean every 1 out rm90  (rm100 - rm10)

rm90*3+bell boy rm20=290

where is the balance RM10?
