An integer is randomly selected from 101 to 751. What is the probability that the selected number is an olive number?
1. An olive number is an even multiple of 13.
2. An olive number must be divisible by 26.
Aabhash777, the Jamboree instructor is wrong.
TithiMarodiaNot very fond of the question, but if I have to find a solution
1. An olive number is an even multiple of 13.
This tells us that Olive number = even multiple of 13.
So possible solutions are 8*13, 10*13, 12*13.
Sufficient
2. An olive number must be divisible by 26.
The wording tells us that being divisible by 26 is just one property. a) It could be that the olive number is a multiple of 52, so 8*13 and 12*13.
b) It could be that the olive number is a multiple of 26, so 8*13, 10*13 and 12*13.
Both the above examples satisfy the conditions of statement II.
Insufficient
A
We are to be tested on mathematical applications and not on verbal reasoning, so not a great question.
