If the cost of 10 tables and 15 chairs is Rs.20000 what will be the cost of tables and 21 chairs?

Answer»

Rs. 28000



The cost of 10 tables + 15 CHAIRS = Rs.20000

Multiplying each TERM by 7/5, we get

Cost of 10 X 7/5 tables + 15 x 7/5 chairs = Rs.20000 x 7/5

= 14 tables + 21 chairs = Rs.28000.
