1. Ans.b. In 97 no. of NMG purchased are 30 so in 99, 20% of these i.e., 6 will be disposed off it means 24 are carried forward, 50 are purchased in 98. So total no. of NMG purchased in 99 will be 124-(50+24) =50.
2. Ans.b. In 99 no. of disposed off NMG =6. In 2000 the no. of disposed off NMG will be 20% of newly purchased in 98 i.e., 20% 0f 50 =10. Total no. of disposed off NMG by end of 2000 will be 16.
3. Ans.a. As 10 Purana mixer grinders were purchased in 1997 and difference between 1996-97 Purana brands is 182 –162 =20. So total mixer purchased in 1997 =20 +10 =30. 20% of 30 = 6.So 6 Purana brands were disposed off in 1999. So total purchased in 1999 = (236-222) + 6 =14+6 =20.
4. Ans.e. Since we don’t have any idea, how many Purana mixer grinder were disposed off in 2000. We can’t calculate this also, as we don’t have again knowledge of no. of purchase or disposed of in year 1998 or 96.So answer cannot be determined.

Guess I am being blind here. I do not see where there is a purchase of 30 NMG mentioned anywhere here, as per your firs answer. Its only in 98 I see not 30, but 80 units bought. Correct if I am not looking at it properly. Thanks.
