Question

find the value of (4/7)²×(4/7)-³ = ?​

Answer 1

Step-by-step explanation:

Let the cost price (CP) be Rs 100

Marked price = CP + 20% of Cost Price

Marked Price =(100+20)% of 100=100+

20

×100=120

Discount of 15% on marked price is given

Hence, selling price = Marked Price - 15% of Marked Price

Selling Price = 120−

100

15

×120 = 120−18= Rs 102

Profit =SP−CP=102−100=Rs 2

Now, Profit Percent =

CP

Profit

×100=
