Solution
The correct option is B Shop 2
To pick the best deal we need to estimate the cost of 1 kg banana for each shop
Shop 1 :
₹ 41 can be rounded off to ₹ 40
Cost of 1 kg banana = ₹40 ÷ 4
= ₹10
Shop 2 :
₹ 34 can be rounded off to ₹ 30
Cost of 1 kg banana = ₹30 ÷ 5
= ₹6
Since ₹6 is less than ₹10
So shop 2 will be a better option for Rani to purchase bananas.
