Question:
Three items are purchased ar Rs450 each. One of them is sold at the loss of 10% At what price should the other two be sold so as to gain 20% on the whole transaction What is the gain% on these 2 items.. ​

Answer 1

Hi friend!!

Total cost for purchasing three items= 450×3=1350.

Selling price of 1st item=450-(0.1×450)=405

Total selling price when gained 20%

=1350+(20/100 ×1350)=1620

Price for each of the two items to gain 20% on the whole transaction =(1620-405)/2

=607.5

gain percentage on the two items =(1215-900)/900 ×100=35%

I hope this helps you;)

Hello mate!

Solution:

C.P of one item = Rs 450

S.P of three items = Rs 450*3 = Rs 1350

Gain on whole transaction= 20% of S.P

$\frac{20}{100} \times 1350 = rs270$

S.P of three items = 1350+270 = Rs1620

It is given that first item is sold at loss of 10%

Loss on selling first item = 10% of 450

$\frac{10}{100} \times450 = rs45$

S.P of first item = 450-45 = RS 405

S.P of 3 items is RS 1620 and S.P of first item is Rs 405

S.P of remaining 2 items = 1620-405= Rs1215

C.P of remaining 2 items= 2*450=Rs900

Gain on remaining 2 items= 1215 - 900

= RS 315

Gain %

$(\frac{315}{900} \times 100)\%$

$35\%$

Hope this helps dear ☺️
