Answer 1

Answer:

The table cost Rs 294

Step-by-step explanation:

let the cost of the table be denoted as $x$

then, the cost of table and tray is $x+30$

If the table is sold for Rs 405 and the tray given for free,

then,

the amount received after sale for both items is Rs 405.

If the profit made is 25% ,

the,

the selling price is 125% of the cost .

If 125% = Rs 405

100%= ??

$cost=\frac{405}{125} *100=324$

The total cost of the two items is Rs 324

we know that the tray costs Rs 30

therefore the table must be (324-30=294)

or

x+30=324

x=324-30

x=294

The table cost Rs 294
