Answer: 26
Step-by-step explanation:
10 : 3 means for every 3 songs he kept, he deleted 10
He deleted 20
10 * 2 = 20
3 * 2 = 6
He deleted 20 songs, and kept 6.

Step-by-step explanation:
Work=speed times time (my equation to help me figure it out)
ok, 10 men take 84 days to complete a job
therefor, each man completes 1/10 of the job in 84 days
each man does 1/840 of the job per 1 day
so, if we had 5 more, or 15 men
15 times 1/840 times xdays=1 job complete
15/840 times xdays=1job
times both sides by 840/15
xdays=840/15
xdays=56
56 days it would take
