CAT 2017 Quant Slot 1 Solution (Hypothetical Example)
Note: Since the exact question isn’t provided, here’s a template for solving a common Quant problem type from CAT 2017, such as a Data Interpretation (DI) or Algebraic Equation.
Problem Statement (Hypothetical):
A company’s revenue over 5 years is given in a bar graph. The revenue in Year 3 was 20% less than Year 2, and Year 5’s revenue was 15% of Year 4’s. If the total revenue for Years 2–5 was ₹24,000 crores, find the revenue in Year 3.
Solution Steps:
Define Variables:
Let Year 2 revenue = ( x ).
Then, Year 3 revenue = ( 0.8x ) (20% less than Year 2).
Let Year 4 revenue = ( y ).
Year 5 revenue = ( 0.15y ) (15% of Year 4).
Total Revenue Equation:
( x + 0.8x + y + 0.15y = 24,000 )
Simplify:
( 1.8x + 1.15y = 24,000 )
Additional Information (if provided):
If Year 1 revenue = 10% of Year 2, or other relations, use them to solve for ( x ) and ( y ).
Solve for ( x ) and ( y ):
Example: If ( y = 2x ) (hypothetical relation):
Substitute ( y = 2x ):
( 1.8x + 1.15(2x) = 24,000 )
( 1.8x + 2.3x = 24,000 )
( 4.1x = 24,000 )
( x = \frac{24,000}{4.1} ≈ 5,853.66 )
Year 3 revenue = ( 0.8x ≈ ₹4,682.93 ) crores.
Final Answer:
Year 3 revenue ≈ ₹4,683 crores.
Key Tips for CAT Quant:
Data Interpretation:
Calculate % changes using (\frac{\text{New Value}}{\text{Old Value}} \times 100).
Use ratios (e.g., 20% less = 4:5 ratio).
Algebraic Equations:
Assign variables to unknowns.
Form equations from relationships (e.g., "A is 20% of B" → ( A = 0.2B )).
Time Management:
DI questions take 10–15 minutes. Double-check units (e.g., crores vs. lakhs).
Check for Consistency:
Ensure percentages are applied to the correct base year.
