Step-by-step explanation:
Let original cost of each toy be 100 Rs.
Number of toy originally sold be 100
After increasing the rate by 20%
New cost = 100+(100×
100
20
)=120
Number of Toy sold =100−15=85
Therefore original sale proceeds = 100×100=10000
Therefore New sale proceeds = 120×85=10200
increase% =
10000
((10200−10000)×100)
⇒2 % increase
