Answer 2

Answer:

Milk should be sold in 188Rs

Step-by-step explanation:

We had given that milk is of 150Rs and we have to earn 20% profit on it.

Therefore we must use hit and trial method to find the cost, We will start from 190, $190\times\dfrac{20}{100}$=38, which is 152Rs

Now we will check for 189$189\times\dfrac{20}{100}$=39

Now we will check for 188$188\times\dfrac{20}{100}$=38

i.e. 188-38=150, Hence we get our number

We should sell milk in 188Rs for making 20% profit
