Kids homework!!

Mike - I don't think you can score 99 in 3 darts with that combination.

Opps i missed the 8 from the list

7 numbers:

1, 2, 4, 8, 16, 32, 64.

Your right 99 cannot be got in three.

back to the drawing board

Mike, good but you'd surely need more than 3 darts for some numbers. 15 for example.

Mike - I thought it would be that sort of solution too, but having to use exactly 3 darts each time really does make it trickier!

My attempt is 18:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 32, 64

My best so far is 13:
1,2,3,4,5,6,7,8,9,10,20,40,50

 

[Peter_SSs]

Good improvement!

 

[cornflakegirl]

Okay, now down to 11:

1,2,3,4,5,10,15,20,40,60,80

or

1,2,3,4,5,10,15,20,25,50,75

Do you have to actually use all three darts, and score with them ?
For example, if the target value is 4, and one of the segments is 4, can you achieve it by using one dart in 4, and not throwing the other 2 (or letting them miss) ?
Or, do you have to make 4, for example, by using a 2 and two 1s ?

Are you asking that because you're rubbish at darts?

Assume as simple an answer as possible, I will reveal age later as it is quite surprising!!

Good luck

I really hope it's not a primary school child. If it is, you probably need to shoot the teacher for trying to put kids off maths - enough of them hate it already!
