उत्तर

a. The above double bar graph compares the sale of brands A and 6 during the months of January to June.

b. We can clearly see from the double bar graph that sales for brand A reduced in the month of March compared to that of February.

c. Sales of brand A in June = 157 lakh and sales of brand 6 in June = Rs. 54 lakh

Difference in sales = 57 – 54 = Rs. 3 lakh

d. Average sales of Brand B = `"Total sales of brand B in six months from January to June"/6`

= `(36 + 38 + 43 + 35 + 45 + 54)/6`

= `251/6`

= ₹ 41.83 lakh

e. We can clearly see from the double bar graph that sales of brand S is less than sales of brand A in the month of April and June.

f. Sales of brand A in January = 31 and sales of brand S in January = 36

∴ Required ratio = 31/36 or 31: 366
