Hi Guys, How to prepare for DILR in an effective way ... Solving each and every question now won't help me!! All ur suggestions will be appreciated.
A farmer earns money on the basis of the following conditions. A cow costs Rs.5000 and gives milk for 80 days in the year. Every day a cow gives 1 litre of milk. A bull costs Rs.10000.
