Step-by-step explanation:
a) 15/100 × 8400 = 1260
therefore , 1260 inhabitants are in the school
b) 74/100 × 8400 = 6216
therefore , 6216 inhabitants are under 60
c) since the new population is added to the existing population
new population = existing population + 4% of existing population
new population = 8400 + 4/100 × 8400
= 8400 + 336
= 8736
