Question

a machine is sold at a profit of 10%had it been sold for rs 80 less there would have been a loss of 10% then cp of the machine is ​

Answer 1

Solution :-

let CP be x

then SP =1.1x(considering 10% gain)

again,

SP =x-((10/100)*x) =0.9x (considering 10% loss)

now,

1.1x-0.9x=80

so ,

x= 400

then cp of the machine is 400 ₹
