59. How Many Goats Remain? You start with 27 goats.• 15 % of the adult goats become pregnant (round to the nearest whole goat).• Each pregnant goat gives birth to 7 kids.• Sadly, 62 % of the kids die (again, round to the nearest whole goat).After all this, how many goats are left alive in the herd? Added 22 April 2009 Show Hint Show Solution Hint: Work in stages: (1) find how many adults are pregnant, (2) work out how many kids are born, (3) subtract the kids that die, then add the survivors to the original adults. Solution: 1. Pregnant adults: 15 % of 27 = 4.05 → 4 goats (rounded). 2. Kids born: 4 × 7 = 28 kids. 3. Kids that die: 62 % of 28 = 17.36 → 17 kids (rounded). 4. Kids that survive: 28 − 17 = 11 kids. 5. Total goats left: original 27 adults + 11 surviving kids = 38 goats.
