Answer 2

Answer:

RS 50,000

Step-by-step explanation

let c.p 100 x for a

then a sells to b at 10 loss

i.e 100 x= 90 x

then b had to pay only 90

now b sells at 20% profit

i.e 90 x = 108 x

given s.p for b =54000

but we have b=108 units

i.e 108 x=54000

x=500

so,original c.p of a was 100 x...i.e rs 50000
