Question

2. Radha purchased a watch at 20% discount on its marked price, but sold it at the marked price. Find
the gain per cent of Radha on this transaction.​

Answer 1

Answer:

25 %

Step-by-step explanation:

Let the Market Price of the Watch (M.P.) be x

∴ CP for Radha = x - [ ( 20 / 100 )*x ]

∴ CP = ( 1 *x ) / 5

= 4x/ 5

5∴ SP for Radha = MP = x

= MP = x∴ Difference ( Profit ) = SP - CP

= x - ( 4x / 5 )

= ( 5x - 4x ) / 5

= x / 5

5Profit % = ( Profit / CP ) * 100

∴ Profit % = ( x / 5 ) / ( 4x / 5 ) * 100

[ Solving ]

Profit % = 25 %
