Answer 1

(a) The double bar graph represents the information about the comparison sales of two brands A and B during January to June.

(b) Sales of Brand A in the month of March is less than sales in the month of February.

∴ In the month of March, sales of Brand A decreased as compared to the previous month.

(c) Sales of Brand A in the month of June = ₹ 57 lakh

Sales of Brand B in the month of June = ₹ 54 lakh.

Difference in sales = ₹ 57 lakh – ₹ 54 lakh = ₹ 3 lakh

(e) In the month of April and June, the sales of Brand B was less than that of Brand A.

(f) Sales of Brand A in the month of January = ₹ 31 lakh

Sales of Brand B in the month of January = ₹ 36 lakh

∴ Required ratio = 31/36 i.e., 31 : 36.
