Title: DILR 2020 Slot 3: Data Interpretation and Logical Reasoning Solutions
(Note: This is a generalized guide based on common DILR question patterns. Actual 2020 Slot 3 questions may vary.)
1. Data Interpretation (DI) Section
Sample Question (Hypothetical):
A bar graph shows the annual sales (in ₹ crores) of five companies (A, B, C, D, E) across three years (2018–2020). Answer the following:
a) Which company had the highest average sales from 2018–2020?
b) In 2019, which company’s sales were 25% less than the total sales of Companies A and B combined?
Solution:
Calculate Average Sales for Each Company:
Company A: (2018 + 2019 + 2020)/3
Repeat for B, C, D, E.
Result: Company C leads with ₹150 crore average.
2019 Sales Analysis:
Total sales of A + B in 2019 = ₹120 + ₹150 = ₹270 crore.
25% less = 270 × 0.75 = ₹202.5 crore.
Result: Company D’s 2019 sales = ₹202.5 crore.
2. Logical Reasoning Section
Sample Question (Hypothetical):
Five friends (P, Q, R, S, T) attend a conference. Each person enters the venue at different times. Using the following clues, determine the order of entry:
Clues:
P enters after Q but before S.
T enters after R.
Q does not enter first.
Solution:
List Constraints:
Q < P < S
R < T
Q ≠ 1st.
Possible Arrangements:
Start with Q (since Q ≠ 1st).
Q → P → S.
R and T must fit after Q but before S or after S.
Valid Sequence: Q (2nd), R (3rd), P (4th), T (5th), S (6th).
Wait, this contradicts Q < P < S. Correct sequence:
Final Order: Q (2nd), R (3rd), P (4th), S (5th), T (6th).
3. Answer Key (Hypothetical)
DI Answers:
a) C
b) D
LR Answers:
Q, R, P, S, T
Exam Strategy for DILR
DI Tips:
Skim graphs/charts first; note units (e.g., ₹ crores).
Use approximations for quick calculations (e.g., 25% of 270 ≈ 202.5).
LR Tips:
Translate clues into inequalities (e.g., P > Q, S > P).
Use process of elimination for sequences.
Time Management:
Allocate 20 mins for DI (25 questions) and 20 mins for LR.
