This one is a data sufficiency question in Algebra - Linear Equations. The question tests your ability to determine one of the variables uniquely from the information given in two statements. A shop sells lubricants in 50-litre and 10-litre containers. If the total volume of lubricants sold by the shop in a day was 280 litres, how many 10-litre containers did the shop sell in the day? Statement 1: The shop sold less than ten 10-litre containers on that day. Statement 2: The shop sold more than three 50-litre containers on that day.

Question A shop sells lubricants in 50-litre and 10-litre containers. If the total volume of lubricants sold by the shop in a day was 280 litres, how many 10-litre containers did the shop sell in the day? Statement 1: The shop sold less than ten 10-litre containers on that day. Statement 2: The shop sold more than three 50-litre containers on that day.
Step 1 Get clarity on when the data is sufficient
How many 10-litre containers did the shop sell? We will not even look at the statements while answering the following questions When is the data sufficient and when not?
How many 10-litre containers did the shop sell? We will not even look at the statements while answering the following questions When is the data sufficient and when not? The data is sufficient if we can determine uniquely the number of 10-litre containers sold by the shop.
How many 10-litre containers did the shop sell? We will not even look at the statements while answering the following questions When is the data sufficient and when not? The data is sufficient if we can determine uniquely the number of 10-litre containers sold by the shop. If the information in the statement(s) results in more than one value for the number of 10-litre containers sold, data is NOT sufficient.
