Question

TIMSS tickets for a concert cost either 10Zeds,15Zeds or 30Zeds. Of the 900 tickets sold 1/5 cost 30Zeds and 2/3 cost 15Zeds each. What fraction of the tickets sold for 10Zeds each?

Answer 1

Answer:

Fraction is 180/900, or 1/5

Step-by-step explanation:

Price (Zeds)      Sold          Sold

    10                   X                  X

    15                 (1/5)*900       600

    30                (2/3)*900      120

Total                  900               900    

X + 600 + 120 = 900

X = 180

Fraction is 180/900, or 1/5
