Mr Brown spent $490 of his salary on a DVD player. The remaining money was given to his wife and used for paying the household bills in the ratio 3:2. If he used 1/6 of his salary to pay the household bills, how much was his total salary?

let x be his salary

     x/6 = household bills

3y + 2y = x - 490

        5y = x - 490

1/2 (2y = x/6)

         y = x/12

     5 (x/12) = x - 490

     5x/12 - x = - 490 

     \( {5 - 12 \over 12}x\) = - 490

      (-7/12x = -490)(-12/7)

              x = \(\boxed{840}\)
