Chestnuts

Three divisions of nature protectors participated in the collection of chestnut trees.1. the division harvested 1250 kg, the 2nd division by a fifth more than the 1st division and the 3rd division by a sixth more than the second division. How many tons of chestnuts did they collect in total?

Correct result:

x =  4.5 t

Solution:

$$\begin{gathered} a=1250\text{ kg } \\ b=a+a\mathrm{/}5=1250+1250\mathrm{/}5=1500\text{ kg } \\ c=b+b\mathrm{/}6=1500+1500\mathrm{/}6=1750\text{ kg } \\ d=a+b+c=1250+1500+1750=4500\text{ kg } \\ x=d\to \text{ t}=d\mathrm{/}1000\text{ t}=4500\mathrm{/}1000\text{ t}=4.5\text{ t}={\displaystyle \frac{9}{2}}\text{ t} \end{gathered}$$
