A child’s toy usually costs $30.40 in a sale the price is reduced by 40% . What is the price of the toy in the sale now ?

Answer 1

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
