At midnight on Sunday 31 December, two analogue clocks were set at the correct time.
One clock gains one minute every hour the other clock loses two minutes every hour.
(1) When will the clocks next show the correct time as each other ?
(2) When will the clocks both show the correct time ? GOOD LUCK

I did:
3 mins difference every hour.
72 mins gaps after 24 hours (1 day).
360 mins (6 hour) gap after 5 days
12 hour gap after 10 days.
I suppose clock A has gained 240 hours after 10 days. So it shows 4.00 am
Can't be bothered with last bit- oh I suppose it's 3 x as much (assuming it's a 12 hour clock not a 24 hour clock). So that's 12.00 noon on the 30th Jan
