      Solution

      Rohit's investment: 1000 [32 + (34+36+38+40) + (38+36+34+32+30+28+26)]
      = 1000 [32 + 148 + 224]
      = 1000 [404] = ₹4,04,000

      Dev's investment: 1000 [18 + (20+22+24+26) + (24+22+20+18+16+14+12)]
      = 1000 [18 + 92 + 126]
      = 1000 [236] = ₹2,36,000

      Meera's investment: 7 × 60,000 = ₹4,20,000

      Ratio of Profits: 404 : 236 : 420

      Difference in the shares of Meera and Rohit:
      {(420-404) × 2,65,000}/(404+236+420)
      = (16 × 2,65,000)/1060 = ₹4,000
