adults=a
teenagers=t
given a/t = 1/30----------------(1)
teenagers increased by fifty that means t+50 and adults by 5 that means a+5
the new ratio will be
t+50/a+5 = 1/25------------(2)
from eqn (1) ....t=a/30
put this value in eqn (2)

so,
25(a/30 + 50) = a+5
5a/6+1250 = a+5
a/5= 1245
a=6225

Is this solution Helpfull? Yes (1) | No (20)
