B’s method : Divide the set into 2,000 and 3,000 numbers, take average in each set and then take the average of the averages.
C’s method : 500 numbers were unities. He averaged all other numbers and then added one. Are these methods correct ?

4. In a class of 50 students, there are 30 boys and 20 girls. In a test, the average marks obtained by boys was computed to be 40‘ and those by girls to be 45.

15. Smoking, consuming high-calorie fast food and alcohol, will not only cut short life-span but will also cost the country dear. A report jointly prepared by WHO and the WEF says India will incur an accumulated loss of \$ 236·6 billion by 2015 due to unhealthy lifestyle and faulty diet. The resultant chronic diseases like heart disease, paralytic stroke, cancer, diabetes and respiratory infections will severely effects people earnings. The income loss to India due to these diseases, which was \$ 8-7 billion in 2005, is estimated to rise to_\$ 54 billion in 2015. It is much more in China. According to a report by World Health Assembly (WHA), 60% of all deaths worldwide in 2005, i.e. 35 million deaths resulted from non-communicable diseases (NCDs) and accounted for premature deaths. This number is likely to rise to 47 million deaths in a year, in the next 25 years. What is worrying is around 80% of these deaths will occur in low and middle income countries like India ? Almost half of those who will die from chronic diseases will be in their productive years.

The cost to employers of morbidity attributed to NCDs is increasing rapidly. Work-places should make possible healthy food choices and support physical activity. Unhealthy diet, excessive energy intake, physical inactivity and tobacco use are major risk factors for NCDs.

The study cited scientific evidence that healthy diet and adequate physical activity at least 30 minutes per day for at least five days a week helped to prevent NCDs. in India, 10% of adults suffer from hypertension while the country is said to have 25-30 million diabetics. 3 out of 1000 people suffer from a paralytic stroke. The number of deaths from heart attack is projected to increase from 12 million to 2 million in 2010. Let us prevent this situation and make India more healthy.
