The cost of making a robot consists of material cost,repairing cost,coloring cost and is in the ratio 3:4:5.if the material cost is 1200 then find out the cost of the robot.

• according to he ratios, let material, repairing and coloring costs are 3x 4x and 5x respectively.
  since, 3x is given as 1200, so x=400.
  so total cost of robot is 12x i.e. 4800

• cost of robot=3x/3+4+5
  3x/12=1200
  then x=12*1200/3
  x=4800 ans

• let total cost =x
  acc to the ratios material costs: 3% of (x)=1200 => x=40000
  now repairing: 4% of 40000=1600
  coloring: 5% of 40000=2000
  so total cost=1200+1600+2000=4800
