Question

Sunita made a profit of 15% by selling a shirt at a profit of rupees 150 find cost price​

Answer 1

Answer:

Rs 200

Step-by-step explanation:

Let the cost price =x; selling price =115%(x)

New cost price =95% (x); New selling price=115% (x) −21

But new SP=110% of new CP

=110% (95% x)

therefore

110%(95% x) =115%(x)−21

104.5%(x)=115%(x)−21

10.5%(x) =21

∴ x=  

10.5

21

​  

×100=200

∴ Cost of the shirt =Rs. 200

Answer 2

Answer:

Let the cost price =x; selling price =115%(x)

New cost price =95% (x); New selling price=115% (x) −21

But new SP=110% of new CP

=110% (95% x)

therefore

110%(95% x) =115%(x)−21

104.5%(x)=115%(x)−21

10.5%(x) =21

∴ x=10.521×100=200

∴ Cost of the shirt =Rs. 200
