the blood alcohol concentration(BAC)in the uk is 0.08%. A well known formula for calculating BAC percentage is widmarks formula
BAC%=5.14A/rW -0.015H
Where A is the total alcohol consumed in ounces, W is the body weight in pounds, r isthe alcohol distribution ration (0.73 for men, 0.66 for women) and H is the time passed in hours since drinking commenced.
A man has a BAC of 0.1%, he has consumed 4 pints of medium strength beer (4%abv) if he weighs 12.5 stone, how long ago did he begin drinking?

you have the formula, and you have the numbers. What's the trouble? (aside from converting stones to lbs)

Since the formula says BAC% = ... I'd say just set it up as
0.1 = (5.14)(4*16*.04) / (.73)(12.5*14) - 0.015H
H = 0.2 hours
0.1 = (5.14)(4*16*.04) / (.73)(12.5*14) - 0.015H
H = 0.2 hours
