Answer 1

Answer:

14,000

Step-by-step explanation:

Sale price = Rs.16,800

Loss % = 20

Loss = Cost price - sale price

Loss = Cost price - 16800

Loss % = ( Loss/ cost price) x 100

⇒ 20 =[ ( Cost price - 16800 ) / cost price ] x 100

⇒ 1 = [ ( Cost price - 16800 ) / cost price ] x 5

⇒ 1 x cost price =  ( Cost price - 16800 ) x 5

⇒ cost price = 5 cost price - 84000

⇒ 84000 = 5 cost price + cost price

⇒ 84000 = 6 cost price

⇒ 84000 / 6 = cost price

⇒ 14000 = cost price

⇒ cost price = Rs.14,000
