Salaries of Ashwath, Bindu and Chethan are in the ratio 5:6:7. Difference in the product of salaries of Ashwath and Bindu and Bindu and Chethan is 12,000,000. What is the sum of the three salaries?

• a:b:c = 5:6:7
  Ashwath(a) = 5x
  Bindu (b) = 6x
  Chethan(c) = 7x
  
  bc-ab = 12000000
  => b(c-a)= 12000000
  => 6x(7x-5x)= 12000000
  => 12*x^2 = 12000000
  => x = 1000
  
  a+b+c = 5x+6x+7x = 18x = 18*1000 = 18000

• let 5x,6x,7x be their salary.....
  according to ques 42x^2-30x^2=12000000
  therefore x=1000
  and therefore sum=18000 is the final answer

• let ashwath sal=5x
  bindu sal=6x
  chethan sal=7x
  (6x*7x)-(5x*6x)=12,000,000
  on solving this equation
  x=1000
  hence sum of three sal=5000+6000+7000=18,000

• let salaries of ashwath,bindu,chethan be 5x, 6x and 7x respectively
  hence bindu*chethan - ashwath*bindu
  => 42*x^2 - 30*x^2 = 12000000
  => 12*x^2 = 12000000
  => x = 1000
  => sum of salaries 5x+6x+7x= 18x = 18000
