Kiran marks the sari at Rs X

He will discount it 10%

Therefore he will be paid 100%-10% or 90% of x, 
which is 0.9x

He wants to gain Rs 0.20(3000)


    (Gain) =  (Money he will be paid) - Cost

0.20(3000) = 0.9x - 3000

       600 = 0.9x - 3000
      3600 = 0.9x
      3600%2F0.9 = x

      4000 = x

Kiran should mark the sari Rs 4000
