Question

In a forest there are some birds and trees are there and if one bird is sitting on 1
tree then 1 bird is left if 2 birds are sitting on 1 tree then 1 tree is left how many birds and tree are there?​

Answer 1

Explanation:

Let the number of

birds

first tree be x and second tree be

x-=y+1

x + 1 = 2(y - 1)

eq - 0

x = y + 2

Substituting the value of a in we partial^ +

x + 1 = 2y - 2

y + 2 + 1 = 2y - 2

⇒ y + 3 = 2y - 2

2y - y = 3 + 2

+) y = 5

Substituting y = sin x = y + 2 /5x=5+2 =7*

7 birda are frost tree.

5 birds

are

on

second

we get,

y.

from

tree.
