The following graph shows the production of cotton cloth (in lakh metres) by three companies A, B and C over five years.

In which years was the average production of the companies, more than 38 lakh metres?

As we know, 

$$Average=\frac{sum\ of\ observation}{Number\ of\ observation}$$

The average production of companies of A, B and C  in different years : 

• 1996 :

= $$\frac{24+22+40}{3}=22\ lakhs$$ 

• 1997 : 

$$=\frac{29+23+62}{3}=38\ lakhs$$

• 1998 : 

$$=\frac{24+38+59}{3}=40.33\ lakhs$$

• 1999 : 

$$=\frac{57+49+51}{3}=52.33\ lakhs$$

• 2000 : 

$$=\frac{45+55+53}{3}=50.66\ lakhs$$

So, The average production of the company is more than 38 lakhs in 1998, 1999 and 2000.
