उत्तर
a. The above double bar graph compares the sale of brands A and B 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 B 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 B 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 B in January = 36
∴ Required ratio = `31/36` or 31: 366
