Answer 1

Step-by-step explanation:

Let bird number is X

according to question

X+1/2X+1=y(y is natural number)

Answer 2

Answer:

no of birds=x=2,4.6.8,10,.............................

Step-by-step explanation:

LET NUMBER OF BIRDS=x

then y= x+x+x/2+1 is a natural number

y=2x+x/2+1

y=5x/2 +1  is a natural number`

y is a natural number

if 5x/2 is a natural number

or x/2 is a natural number

or x is an even number

x=2,4.6.8,10,.............................
