Question
What is the ratio of number of cars sold by X, Y and Z
in the 3rd Qtr. to the number of cars sold by V, W and Z in the 1stQrtr?Solution
No. of cars sold by X, Y and Z in the 3rdQrtr. = 25 + 75 + 100 = 200 No. of cars sold by V, W and Z in the 1stQrtr.= 25 + 100 + 250 = 275 Reqd. Ratio = 200: 275 = 8:11
