DI Word Problems: The Cryptic Analyst

Five Companies A, B, C, D and E saw growth rates ranging from 10% to 50% in the year 2015. The company A with the least revenues of Rs. 600 crores in 2015 saw the maximum growth rate of 50% and the Company D with the highest revenue saw the least growth rate of 10%. Company B’s revenues in 2016 was equal to that of Company D in 2015, while Company C’s 2016 revenue was equal to that of Company B’s in 2015, Company A’s 2016 revenue was equal to that of Company E in 2015.

John, an accountant observes that one of the companies has twice the growth rate of another. Mathew, his colleague corrects him and says that this is the case in two different instances.

Company E has a revenue equal to the average seen in Company A and D, and growth rate equal to the average growth rate of A and D.

General Solution

We are going to construct and fill a table with details that we can infer from the statements. Company A has Revenues of Rs. 600 crores and sees a growth rate of 50%. Let Company D’s revenue in 2015 be X. The revenue of Company B in 2016 should also be X. Let revenue of Company B in 2015 be Y, this should be equal to revenue of Company C in 2016. Let us capture this in a table:

Company A’s 2016 revenue was equal to that of Company E in 2015.

The next statement that is very useful is “Company E has a revenue equal to the average seen in Company A and D, and growth rate equal to the average growth rate of A and D.”. So, Company E should have seen a growth rate of 30%. Revenue of Company D should be Rs. 1200 crores:

Or, if Company C had grown by 50%, it would have reached a revenue of X. Or, Company C had a revenue of 2/3 X in 2015.

Now, we move to these two statements – “John, an accountant observes that one of the companies has twice the growth rate of another. Mathew, his colleague corrects him and says that this is the case in two different instances.” Among the three % growths we already have, none is twice any other. So, the other two growth rates seen in B and C should somehow incorporate this.

So, the growth rates seen in B and C should be from either 2 * growth rates of A, D or E or ½ of growth rates seen in A, D or E. But since the growth rates should be between 10% and 50%, the only possibilities we have are 15%, 20% and 25%.

From the numbers, we can see that Company C should have grown by 25% and Company B by 20%

Solution to Question 2
