Так как Коля начал брать конфеты первым , то он всегда брал конфеты нечетное количество раз:
Взял Коля:
1 раз: 1
2 раз: 3 (1+3=4)
3 раз: 5 (4+5=9)
4 раз: 7 (9+7=16)
5 раз: 9 (16+9=25)
6 раз: 11 (25+11=36)
7 раз: здесь Коля не смог бы взять 13 конфет (т.к. 36+13>37) , соответственно он взял одну конфету и закончил пакет.
Оля брала каждый раз четное число конфет , всего она взяла конфеты 6 раз:
1 раз: 2
2 раз: 4 (2+4=6)
3 раз: 6 (6+6=12)
4 раз: 8 (12+8=20)
5 раз: 10 (20+10=30)
6 раз: 12 (30+12=42)
Соответственно Оля взяла 42 конфеты, а Коля 37
