Question

A man bought 24 tables and sold them at a gain equal to the selling price of 4 tables.find his gain percent? ​

Answer 1

Answer: d)20%

Step-by-step explanation:

Gain = Sp - Cp

As Mentioned Gain = Sp of 4 Tables

so , Gain = 4 Sp

4 S.p  of Tables = 24 S.p - 24 C.p

24 C. p = 24 S.p - 4 S.p

24 C.p = 20 S.p

CP/SP = 20/24

cp=20 k ; sp= 24 k ; k is +ve integer

Gain % =  (Gain / Cp ) *100

              = ( 4k / 20 k ) *100

           Gain %  =20 %
