Question

Banana value 10 percent less now get more for 20 in $9 then calculate the price of reduced kg

Answer 1

Answer:

Step-by-step explanation:

The amount that the person has is constant.

If price reduces by 20%, the quantity that can be purchased will increase by 20/(100–20) = 25%

Now 25% is equivalent to 3.5 kg

so, 100% = 3.5*4= 14 kg

Hence for Rs. 77 he can buy 14 kg.

So, price per kg = 77/14 = 5.5 Rs/Kg
