Don't get it.Fifty minutes ago if it was four times as many minutes past three o'clock, how many minutes is it to six o'clock?

Four times as many minutes ... compared to what?

four times as many minutes as between three o'clock "now" (the time being asked for) .... sorry my working was a bit ambiguous, hope now it is clear.

I think he is saying that if it is x minutes past 3:00 right now, then 50 minutes ago it was 4x minutes past 3:00. Is this correct?

Well it would be less, not more, right? Why I asked.I think he is saying that if it is x minutes past 3:00 right now, then 50 minutes ago it was 4x minutes past 3:00. Is this correct?

But the explanation provided an answer, above.

|------------4xM--------------------------|--------50----------------|-----M----|3:00 now-50 now 6:00

That is pretty correct. But M cannot be 16, otherwise we would have

|------------4xM--------------------------|--------50----------------|-------M----|

3:00 --------------------------------- now-50 ----------------- now ---------- 6:00

---------------------------------------- 4:04 --------------------- 4:54 ---------- 5:10

Sorry - typo. Of course it's 26.That is pretty correct. But M cannot be 16, otherwise we would have

|------------4xM--------------------------|--------50----------------|-------M----|

3:00 --------------------------------- now-50 ----------------- now ---------- 6:00

---------------------------------------- 4:04 --------------------- 4:54 ---------- 5:10

5M+50=180

10M+100=360

M+10=36

M=26
