.......... .

Answer 2

Answer:

no of cats=21, no of dogs = 53

Step-by-step explanation:

let no of dogs be x and no of parrots be y

so, x+y=74

and , 4x+2y=254

a/q

4x+2y=254

=> 2x+2x+2y=254

=> 2x+2(x+y)=254

=> 2x+2(74)=254

=> 2x +148=254

=> 2x=254-148

=> 2x=106

=> x= 106/2

=>x=53

no of dogs =53

no of cats =74-x

=74-53

=21
