Show the answer and explanation
CorrectNot quiteAnswer B
Correct answer: B
Explanation
3 litres = 3,000 ml = 12 small bottles, costing 12 × ₹30 = ₹360.
3 litres = 2 large bottles, costing 2 × ₹160 = ₹320.
Extra cost = ₹360 − ₹320 = ₹40.
Worth noting
₹20 is the extra cost for only 1.5 litres; ₹200 subtracts the price of one large bottle from 3 litres of small bottles.
