Question
Among 120 sweets, 'p' sweets were sold for Rs. 5 each,
while the remaining were sold for Rs. 'q' each. If Rs. 'pq' is added to the selling price of the (120 – p) sweets, the result equals the selling price of 'p' sweets. Determine the ratio of q to p, i.e., find the value of q:p.Solution
ATQ, 5p = (120 – p) × q + pq Or, 5p = 120q – pq + pq Or, 5p = 120q Or, q:p = 1:24
