Q stem: Currently, there are 40 cars in each row of the lot at a car dealership. If the parking spaces are to be widened and lengthened so that only 30 cars fit in each row and fewer rows fit in the lot, how many cars will then fit in the entire lot?
This can be broken down:
Let total no of cars be x and there are total y rows.
40 * y = x
We are changing parking area so that
30 * z = x ; Also z < y
Question is : What is x?
Quote:
(1) There will be 3 fewer rows of cars.
z is less than y; Not suff since no idea about x
Quote:
(2) Currently there are 10 rows of cars.
Now we know value of z, so x = 300. What am I missing here?
OE in past tense is confusing me
Had this St been Currently there are 10 no of cars in each row.
Would this alone be suff?
If you read the question carefully, there are two Scenarios given and in both the scenarios number of cars in each row is given 40 & 30. What is missing is "Number of Rows". Finally you need to find the Total number of cars in the second scenario.
So you need to analyses the statements and try to find out total number of rows in the Second scenario.
Statement 1 gives relationship between number of rows from first and second scenario and Statement 2 gives total number of rows in the first scenario. So combining both these statements you can find total number of rows in the second lot
