Task 1. In Grandpa Wang's orchard, there are fruit trees, including: 240 cherry trees, 260 peach trees, and 130 apple trees. On Tree Day, the students from Little Wang's class, Grandpa Wang's grandson, came to the orchard and planted an additional 75 cherry trees, 126 peach trees, and 142 apple trees.

a) How many students are there in Little Wang's class if each student planted 7 fruit trees?

b) How many fruit trees of each type are there in Grandpa Wang's orchard now?

c) How many fruit trees are there in total in Grandpa Wang's orchard?
Solution. a) On the day of planting, a total of $75+126+142=343$ fruit trees were planted. Since each student planted 7 trees, there are $343: 7=29$ students in the class.

b) There are: $240+75=325$ cherry trees, $260+126=386$ peach trees, and $130+142=272$ apple trees.

c) The orchard has a total of $325+386+272=983$ fruit trees.
