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?

Hello Guest!
What is used in the household accounts in the ratio 3: 2 please?
!
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 = \(\boxed{840}\)
