Question

Soft drinks sell for P8.50 and fruit juice sells for P11.00 each. On a certain day, the number of soft drinks sold was four times the number of fruit juice sold. How many soft drinks were sold if the total income was P900.00?

Answer 1

The number of soft drinks sold was 4 times the number of fruit juice -> On average, every 4 soft drinks sold, 1 fruit juice is.

-> Every P34.00 of soft drinks sold, P11.00 of fruit juice is.

So, the income is P45.00 everytime.

Since the total income is P900.00, the amount of 4 soft drinks and 1 fruit juice sold is 900 : 45 = 20 times

So, there were 20 x 4 = 80 soft drinks sold.

Recheck : 80 x 8.5 + 20 x 11 = 680 + 220 = 900.
