Question

a reduction of 25% in price of the rice enable Mahesh to purchase 4kg more for rupees 600 .find original price ​

Answer 1

Answer:

50

Step-by-step explanation:

Given a reduction of 25% in price of the rice enable Mahesh to purchase 4 kg more for rupees 600 .find original price ​

Let original price be x

So reduction of 25% will be x – 25/100 of x

So new price will be x – x/4 = 3 x/4

Now for Rs 600, Mahesh was able to buy y kg of rice.

 600 = initial price/kg x weight bought = x x y

At new price for same amount he can buy y + 4 kg of rice.

So 600 = new price/kg x new weight

   600 = 3 x/4  x  (y + 4)

   We have 600 = x  x  y

      Substituting y we get

600 = 3 x 600/4 +12 x / 4

600 = 450 + 3 x

3 x = 600 – 450

X = 150 / 3

X = 50  

So the original price was Rs 50
