Difficulty: Easy
Correct Answer: ₹ 3,000
Explanation:
Introduction / Context:
We are given two linear price equations with two unknowns: chair price (C) and table price (T). Solve the system to determine C and T, and then compute the requested bundle price for 4 chairs and 5 tables.
Given Data / Assumptions:
Concept / Approach:
Use elimination. Match the table coefficients by multiplying the second equation by 3 and subtract from the first to isolate the chair price. Solve for C, then back-substitute to find T. Finally compute 4C + 5T.
Step-by-Step Solution:
Verification / Alternative check:
Check both original equations with C = 500, T = 200: 10*500 + 6*200 = 6200 and 3*500 + 2*200 = 1900. Both satisfy perfectly.
Why Other Options Are Wrong:
₹3,300, ₹3,500, ₹3,800, ₹2,900 are not equal to 4*500 + 5*200 = ₹3,000.
Common Pitfalls:
Miscalculating multipliers during elimination or mixing coefficients leads to wrong unit prices; always verify by substitution before finalizing the bundle cost.
Final Answer:
₹ 3,000
