A
small and medium enterprise imports two components A and B from Taiwan and
China respectively and assembles them with other components to form a toy.
Component A contributes to 10% of production cost. Component B contributes to
20% of the production cost. Usually, the company sells this toy at 20% above
the production cost. Due to increase in the raw material and labour cost in
both the countries, Component A became 20% costlier and component B became
40% costlier. Owing to these reasons the company increased its selling price
by 15%. Considering that cost of other components does not change, what will
