Question
Due to reduction of 20% price in wheat, A man can get 10 kg more in Rs 600. New rate of wheat is–
- a. Rs 11.50 / kg
- b. Rs 12 / kg
- c. Rs 12.50 / kg
- d. Rs 13 / kg
Solution
Let's solve this step by step:
Step 1: First, we need to find out the original price of wheat per kg. We know that due to a 20% reduction in price, a man can get 10 kg more wheat for Rs 600. This means that the 20% reduction in price equals the price of 10 kg of wheat.
Step 2: So, if 20% reduction equals Rs 600, then 100% (which is the original price) equals Rs 600 * 5 = Rs 3000. This is because 100% is 5 times 20%.
Step 3: Now, we know that Rs 3000 is the original price for the extra 10 kg of wheat the man can now get. So, the original price per kg of wheat is Rs 3000 / 10 kg = Rs 300/kg.
Step 4: The new price is 80% of the original price (because there was a 20% reduction). So, the new price per kg of wheat is 80% of Rs 300 = Rs 240/kg.
Step 5: Convert the price per kg from Rs to Rs per kg by dividing by 1000 (since 1 kg = 1000 g). So, Rs 240/kg = Rs 0.24/g.
Step 6: Convert the price per g to price per kg by multiplying by 1000 (since 1 kg = 1000 g). So, Rs 0.24/g = Rs 240/kg.
So, the new rate of wheat is Rs 240/kg. However, none of the options (a. Rs 11.50 / kg, b. Rs 12 /kg, c. Rs 12.50/ kg, d. Rs 13/ kg) match this answer. There seems to be a mistake in the question or the options provided.
