A marker bought for Rs 50 was sale at a profit of 5%. find the selling price.

Rs52.5

Step-by-step explanation:

cost price(cp)=Rs50

Percentage profit=5%

Selling price(sp)=?

Percentage profit=(sp-cp)/cp x 100

5=(sp-50)/50 x 100

50 x 5=100(sp-50)

250=100(sp-50)

(sp-50)=250/100

sp-50=2.5

sp=2.5+50

sp=52.5

Selling price=Rs 52.5

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1
