Correct answer: (A) ₹7,000
Adding the two equations (5 chairs+3 tables=12500) and (3 chairs+5 tables=15500) gives 8 chairs+8 tables=28000, so 1 chair+1 table=3500. Hence 2 chairs+2 tables = 2 x 3500 = Rs.7,000.

सही उत्तर: (A) ₹7,000
दोनों समीकरणों (5 कुर्सी+3 मेज़=12500) और (3 कुर्सी+5 मेज़=15500) को जोड़ने पर 8 कुर्सी+8 मेज़=28000 मिलता है, अतः 1 कुर्सी+1 मेज़=3500। इसलिए 2 कुर्सी+2 मेज़ = 2 x 3500 = ₹7,000।
