CAT 2023 Slot 2 — DILR Question 2

Mixed PracticeEasy
Passage / Data

Answer the following questions based on the information given below:

Odsville has five firms – Alfloo, Bzygoo, Czechy, Drjbna and Elavalaki. Each of these firms was founded in some year and also closed down a few years later.

Each firm raised Rs. 1 crore in its first and last year of existence. The amount each firm raised every year increased until it reached a maximum, and then decreased until the firm closed down. No firm raised the same amount of money in two consecutive years. Each annual increase and decrease was either by Rs. 1 crore or by Rs. 2 crores.

The table below provides partial information about the five firms.

​​​​​​​

What best can be concluded about the total amount of money raised in 2015?

Answer & solution

  • A

    It is either Rs. 7 crores or Rs. 8 crores or Rs. 9 crores.

  • It is either Rs. 7 crores or Rs. 8 crores.

  • C

    It is exactly Rs. 8 crores.

  • D

    It is either Rs. 8 crores or Rs. 9 crores.

Solution

Easy

Use the master grid built in Q1 and just read off the 2015 column. Czechy and Drjbna are fixed; the only thing that can vary is Elavalaki.

Recall (from the set-up): Drjbna is fixed as 1,2,4,2,11,2,4,2,1 over 2011–2015, Czechy as 1,2,3,2,11,2,3,2,1 over 2013–2017, Alfloo's 2015 is 22 in both its cases, and Bzygoo's 2015 is 11 (it closes in 2015). Elavalaki either lives through 2015 (Cases 1 & 2, raising 11) or has already closed in 2014 (Case 3, raising 00).

Read the 2015 amounts straight from the grid:

Alfloo=2,Bzygoo=1,Czechy=3,Drjbna=1,Elavalaki=1 (Cases 1,2)  or 0 (Case 3, closed in 2014).\begin{aligned} &\text{Alfloo}=2,\quad \text{Bzygoo}=1,\quad \text{Czechy}=3,\quad \text{Drjbna}=1,\\ &\text{Elavalaki}=1\ (\text{Cases 1,2})\ \text{ or } 0\ (\text{Case 3, closed in 2014}). \end{aligned}
2

Add the four certain amounts, then attach Elavalaki's two possibilities:

2+1+3+1=7,total=7+(1 or 0)⏟Elavalaki=8 or 7.2+1+3+1=7,\qquad \text{total}=7+\underbrace{(1\text{ or }0)}_{\text{Elavalaki}}=8\ \text{or}\ 7.

The total raised in 2015 is either Rs. 7 crores or Rs. 8 crores — option (b).
