The fuel consumption of my car was 17Km/litre on high way but recently it has been reduced to 13Km/litre. What are the possible reasons? Spark Plugs make DENSO were replaced at 60,000 Km. What is the limit in Km of DENSO plugs?

It depends on what plugs were used. If it is normal lugs, it is way past its replacement schedule.
There are many other possibilities and it is best to start with a tune-up.
