This kind of questions are asked every year in both Tier-1 and Tier-2 exam of SSC. Two kind of questions can be asked from this type.

**Type -1 :**When there will be a reduction of price and the purchases will purchase x kg more for y rupees.**Type-2:**When there will be a hike in the price which will force the purchaser to purchase x kg less for y rupees.

__Trick to Solve These Kind of Questions__- First of all find the
**Price per Kg** - Now find the
**Reduced/Increased Price**using the percentage given in reduction or hike. - You can easily find
**Original Price**using the reduced/increased price per kg

**Explanation through Examples****(1) A reduction of 20% in the price of sugar enables a person to purchase 2 kg more for rupees 30. Find the reduced and the Original Price per kg of Sugar?**

Sol - Here questions mentions

*2kg for rupees 30*...so**1 kg will cost Rs 15****Reduced Price**per Kg = (15 x 20)/100 = Rs 3/kg

**Original Price**per Kg = (3 x 100 )/80

Note: while finding the Original Price per kg we have used 80% because it's already mentioned that there was a reduction of 20% in the price i.e 100-20=80.

**(2) A reduction of 10% in the Price of the rice enables a person to purchase 2 kg more for rupees 18. Find the reduced and the Original price per kg of the rice.**

Sol - Here question mentions 2 kg for rupees 18 so ...1 kig will cost Rs 9

**Reduced Price**per kg = (9 x 10) /100 = Rs 0.9/kg

**Original Price**per kg = (0.9 x 100 )/90 = Rs 1/kg

Note: while finding the Original Price per kg we have used 90% because it's already mentioned that there was a reduction of 10% in the price i.e 100-10=80.

**(3) A 10% hike in the price of rice forces a person to purchase 2 kg less for rupees 110. Find the increased and the original price per kg of rice.**

Sol - Here question mentions 2 kg for rupees 100...so 1 kg will cost Rs 50

**Increased Price**per kg

**=**(55 x 10)/100 = Rs 5.5 /Kg

**Original Price**per kg =(5.5 x 100)/ 110 = Rs 5/kg

Note: while finding the Original Price per kg we have used 110% because it's already mentioned that there was a hike of 10% in the price i.e 100 +10=110.
