Pop quiz time!


Data Science, at its core, is all about problem solving. So, have some fun solving these brain teasers!

This will give you an idea about the cool things you will learn when you join us at the Data Science Academy. This quiz is a one-hour aptitude test that tests your problem-solving abilities. It will form the basis of your application and will determine whether you will make it as part of the 2018 intake.

The quiz is best done on a desktop, with a pen and paper to help with the workings. You are welcome to stop and come back to the quiz at any time. You just need to come back to the site, press ‘Apply Now’ and enter the name and e-mail address you used to enter the quiz originally.

Three cats kill 3 rats in 3 minutes. How much time would it take for 100 cats to kill 100 rats?
Sarah thinks of a number. She squares it, takes away 5, multiplies that number by 4, takes away another 7, divides it all by 3 and then finally adds 6. Her answer is 9. What number did she start with?
If ‘AWAKE’ is KAWAE, then SLEEP is
If ADD = 9, BAD = 7, and CAD = 8, then what is the value of ADA?
Solve for the values of X, P, L,O and R where each is a unique integer (i.e. a number from 0 to 9).
XPLOR × 4 = ROLPX.
What is the value of X + P + L + O + R?
What are the number of routes to get from the top left corner to the bottom right corner. You are only allowed to travel on a line and have two - different moves available: right or down. One possible route is given in red below.

In one jar I have two balls labelled 1 and 2 respectively. In a second jar I have three balls labelled 0, 1 and 2 respectively.
I reach a hand into each of the jars, multiply the numbers on the two balls I draw together, and then calculate three to the power of that product, e.g. if I draw 1 and 2, I calculate 3^2=9. Let’s call this number X.
What is the probability that the number 1,024 is an exact multiple of X?
Of a group of students, 26 enjoy reading, 32 enjoy going to the movies and 30 enjoy solving mathematical problems.
Of these, 5 students like all three activities, while 37 like only one of them. How many students like only two of the three activities?
Given this dataset, please select which model best reflects the classification of a new point added to the chart. In other words, if a new point is added to a blue area, it will be classified as a blue dot. If added to an orange area it will be classified as a orange triangle.

A car was involved in a hit and run accident, with Dewald there to witness it. It turns out that 1 in 10 cars on the road is a self-driving car. Dewald said the car involved was a self-driving car. The court tested Dewald's reliability and concluded that he correctly identified what type of car he saw 80% of the time.

What is the probability that the car involved in the accident was a self-driving car, given Dewald's testimony?

Please enter the answer in percentages to the nearest two decimals places: e.g. 50.00%

Hint: you may find Bayes Theorem helpful in getting to your answer…
