Question

If C.P of 30 tables is same as S.P.of 25 tables ,Find the gain percent.

Answer 1

Let the C.P. of each table be Rs 1
C.P. of 30 tables=Rs 30
S.P. of 25 tables=Rs 25
But he takes Rs 30
therefore gain=Rs(30-25)=Rs 5
Gain %=(5/30*100)=50/3 %=16.33% gain.

Answer 2

let the c.p of each table be x
c.p of 30 tables = 30x
s.p of 25 tables =30x=25
                       =30-25=x
 .                      =5=x
. .therefore gain percent = 16.33%
