(1) banana+apple = 150g

(2) As can be seen from the figure,

Poplar = x, willow = 5x -80.

370+80=5x means 5x = 450.

2.( 1)DFG

As can be seen from the figure.

Dad's age = 40 years old

My age = my father's age /4

That is my age = 40/4 = 10 (years old).

Mom's age = my age +25.

That is, the mother's age = 10+25=35 (years)
