Answer 1

Answer:

900

Step-by-step explanation:

Given that each tape costs Rs 375,

Given that 18 desks costs as much as 5 tapes

=> Cost of 18 desks = Cost of 5 tapes

= 5* 375 = 1875 Rs.

Cost of 1 desk will be = 1875/18

= 625/6 Rs.

Given 25 boards costs as much as 15 desks

=> Cost of 25 boards = Cost of 15 desks

= 15*625/6

= 3125/2

So, Cost of 1 board will be = 3125/50

= 125/2 Rs

Given that 10 chairs cost as much as 12 boards

=> Cost of 10 chairs = Cost of 12 boards

= 12*125/2

=Rs 750

So, Cost of 1 chir will be = 750/10

= Rs 75.

Cost of 1 dozen chairs will be

= 75 * 12

=Rs 900.
