So, functional tags = 120 – 30 = <<120-30=90>>90.
Of these, 3/5 transmit incomplete data, so 2/5 transmit complete data: (2/5) × 90 = <<(2/5)*90=36>>36.
Thus, 36 tags provide complete, reliable migration data.
A blockchain developer is designing a token distribution model where 10,000 tokens are allocated: 40% go to early investors, 25% to staking rewards, and the rest split equally among 15 developers for code contribution. How many tokens does each developer receive?
Early investors receive 40% of 10,000 = 0.4 × 10,000 = <<0.4*10000=4000>>4,000 tokens.
Staking rewards receive 25% of 10,000 = 0.25 × 10,000 = <<0.25*10000=2500>>2,500 tokens.
Remaining tokens = 10,000 – 4,000 – 2,500 = <<10000-4000-2500=3500>>3,500.
Each developer gets 3,500 ÷ 15 = <<3500/15=233.333333>>233.333333, which is not an integer. Since tokens are indivisible, the system allocates 233 tokens (rounded down).

A pharmacologist is testing a new Alzheimer’s drug on 300 patients. One-third show significant cognitive improvement, 40% experience mild side effects, and 12% show both improvement and side effects. How many patients showed improvement without side effects?
