Question

Due to 25% hike in the price of rice a women is able to purchase 20 pound less of rice for $ 400. Find initial price _________​

Answer 1

Answer:

20 kg rice

Step-by-step explanation:

Assume, initially the person used to purchase xkg rice for Rs 400, now he purchases (x-20)kg due 25% hike in price ,it means now to purchase x kg rice , the person will have to pay 400+25%of 400=500rs. It's clear that 25%of 400 ( ie Rs 100) is the increased price of 20kg rice.

Therefore, new price of 1kg rice equals to 100/20=Rs5.

125%=Rs 5

100%=(5/125)×100=Rs 4.

Thus original price of rice would be Rs4/kg.

Original consumption of rice=400/4=100k
