      Solution

      ATQ,

      Profit share of X : Y = (12000 ร— 12) : (x% of 12000 ร— 6) = 144000 : (x ร— 120 ร— 6) = 1200 : 6x

      According to question,

      Image

      โ‡’ 6x / (1200 + 6x) = 1 / 6

      โ‡’ 36x = 1200 + 6x

      โ‡’ 30x = 1200

      โ‡’ x = 40

      So, the value of x = 40%
