Answer 2

Answer is 20%

Step by step explanation

Let CP be Rs 100

SP when profit is 8% = 100 + 8% of 100

= 108

Let marked price be Rs X

After giving 10% discount, new SP

= X - 10% of X

= X - 10X

100

= 100X - 10X

100

= 90X

100

The shopkeeper gains 8% after giving discount,so

90X = 108

100

X= 108×100

90

X= 120

Therefore .marked price = 120

Required increase % = 120 - 100

100

= 20%
