I need the answer soon
There was in the forest an old peepal tree
the grand tree has branches ten and three
on each branch there lived birds fourteen
sparrows brown, crows black and parrots green
twice as many as the parrots were the crows
and twice as many as the crows were the sparrows
we wonder how many birds of each kind
are you going to help us find ?
Given, number of branches old Peepal tree has 10 + 3 = 13
Number of birds living on each branch = 14
So, the total number of birds living in the tree = 13 × 14 = 182
Now, consider that the number of parrots be x, crows be y and sparrows be z.
Again, twice as many parrots were crows.
∴ 2x = y
Similarly, twice as many crows were sparrows.
∴ 2y = z
Now, according to the given condition,
x + y + z = 182
⇒ x + 2x + (2y) = 182
⇒ x + 2x + 2(2x) = 182
⇒ x + 2x + 4x = 182
⇒ 7x = 182
⇒ x = 26
∴ number of parrots = x = 26
number of crows = y = 2x = 52
and number of sparrows = z = 2y = 104
