Solution : As per the graph, The total production of company X in the period 1998 - 2000 = 25 + 50 + 40 = 115 lakh tonnes The number of years = 3 The average production of company X in the period 1998-2000 = $\frac{\text{The total production of company X in the period 1998-2000}}{{\text{The number of years}}}$ = $\frac{115}{3}$ lakh tonnes The total production of company Y in the period 1998-2000 = 35 + 40 + 50 = 125 lakh tonnes The number of years = 3 = $\frac{\text{The total production of company Y in the period 1998-2000}}{{\text{The number of years}}}$ The average production of company Y in the period 1998-2000 = $\frac{125}{3}$ lakh tonnes The required ratio = $\frac{115}{3}:\frac{125}{3}$ = 23 : 25 Hence, the correct answer is 23 : 25.
