Answer & Explanation

S1. Ans.(b)
Sol. The percentage rise/fall in production from the previous year for flavor Y during various years are:
S2. Ans.(b)
Sol. Average annual productions over the given period for various flavours are:
For flavour X = [1/6×(50+40+55+45+60+50)] lakh bottles = 50 lakh bottles.
For flavour Y = [1/6×(55+60+50+55+50+55)] lakh bottles
= 54.17 lakh bottles.
For flavour Z = [1/6×(45+50+60+60+45+40)] lakh bottles = 50 lakh bottles.
∴ Maximum average production is for flavor Y.
