If my brother gives my sister 20 yuan, both of them have the same amount of money-then my brother has 40 yuan more than my sister.

Suppose my sister has X yuan and my brother has (X+40) yuan.

(X-25)*2=X+40+25

X= 1 15

Brothers have115+40 =155 yuan.

A: My brothers and sisters have 155 yuan and 1 15 yuan respectively.
