Question

A sells his good 30% cheaper then b and 30% dearer then



c.By what percent is the cost c goods cheaper then b

Answer 1

Answer:

I think that c sells good 30percent cheaper than b

you check like this

let the cp of B be 100

and a sells it 30percent cheaper so the 30 percent of 100 is 30 only

therefore 100-30=70

and the cp of b is dearer than the cp of c

this is the way to confuse here also a same way cp of b is dearer means that the cp of c is less than the cp of b it means it is equal to the cp of a's case so u can copy the a's case here

it means that the cp of c is cheaper than the cp of b by 30percent
