Sample Question. 5 kg of rice and 2 kg of tea cost Rs/- 35, prices of rice grew by 10% and tea by 35% and together I could purchase it for Rs.420. What is the price of tea.
(in these type of questions, whatever is asked take reverse of that, here tea is asked so work on rice.)
Method
350+10% of 350=385
420-385=35
There is a difference of 25%(35%-10%)
This is Rs. 35
25% corresponds to Rs. 35
therefore 100%=140
2 Kg=Rs 140. so 1kg =70
-----------------------------------------------------------------------------------
Example.- I hired a servant for Rs. 300 per month and a cycle if he works for a year. After 8 months I threw him out and paid him Rs. 50 for that month and the cycle. How much does the cycle cost?
Method- In 8 months the servant has earned 2/3rd (8/12) of the cycle. So he is left with just 1/3rd of the cycle, which we will cut in place of 300 we gave him only 50.
1/3 corresponds to (300-50)=250
therefore 1=750. so the cost of the cycle is Rs. 750.

Thankyou for the above information. It was very helpful .
It is for all those who are preparing for the IAS exams. I was preparing for IAS Exam and was looking for regular coaching but was unable to find. Then i opted for the online course for IAS general studies and it was beyond my expectations. It is both time and cost effective. So got myself enrolled at :
