Answer 1

Answer:

Step-by-step explanation:

Let the number of black fishes be x.                                                                     Now, probability of getting black fish=                                                             Total number of black fishes/Total number of fishes⇒1120=x/36+x⇒36×11+11x=20x⇒36×11=9x⇒x=44                                                So, total number of black fishes=44
