from the give options choose the lowest numer which is a multiple of LCM of 2, 5, 6, 12. This is because when all the fractions are multiplied by the number of chocolates you need to get an integer.
LCM = 60

The LCM of 2,5,6 and 12 is 60. If we distribute 60 with the given ratios, it will give
$$\frac{60}{2}+\frac{60}{5}+\frac{60}{6}+\frac{60}{12}=57$$

$$\frac{1}{2} : \frac{1}{5} : \frac{1}{6} : \frac{1}{12}$$ = $$30 : 12 : 10 : 5$$

So, The minimum number of chocolates she should have bought is $$30 + 12 + 10 + 5 = 57$$
