1 Answer

Answer :

Cost of 4 tables =Cost of 10 chairs => Cost of 1 table =10 ÷ 4=2.5 chairs
=>15 chairs + 2 tables = Rs.4000 => 15 chairs + 2 × 2.5 chairs = Rs.4000
=>20 chairs =Rs.4000 => 1 chair = Rs.4000 ÷ 20 = Rs.200
=>cost of 1 tables =2.56 × Rs.200 = Rs.500
Cost of 12 chairs + cost of 3 tables =12 × Rs.200 + 3 × Rs.500 = Rs.2400 +
Rs.1500=Rs.3900
