Solution:

(3) Let the C.P. of each article be Re.1.
Percentage of dishonesty = 10%
(Here x% = 10%)
∴ Actual C.P. =

100/11 0

= Rs.

10/11

∵ He buys 110 articles in Rs. 100.
∵ He sells 90 articles at the C.P. of 100 articles.
∴ Actual S.P. =

100/90

= Rs.

10/9

∴ Profit per cent

= { {10}/{9}-\ {10}/{11}}/{ {10}/{11}} × 100

= {20}/{99} ×{11}/{10} × 100= {200}/{9}

=22 {2}/{9} \%
