Answer 2

Answer:

Number of tickets sold $= 969$

Step-by-step explanation:

According to the problem,

Number of tickets of first class is 15% of the total and that is = 171 tickets

∴ Total number of tickets is 100% of the tickets $= 171 . \frac{100}{15}$

∴ Number of tickets sold:

$= 171 . \frac{100}{15} - 171$ $= 171( \frac{100}{15} - 1)$ $= 171 . \frac{85}{15}$ $= 171 . \frac{17}{3}$ $= (57).(17)$ $= 969$
