Can you explain the answer of this question below:There are 11 more an...
Let number of animals be A
Let number of birds be B.
So first condition we get A=B+11
=> (11+B)4+2B=X
=> 4B+2(B+11)=4X/5
on solving we get B=11 A=22
Hence (C) is the correct answer.

Can you explain the answer of this question below:There are 11 more an...
Given:
- There are 11 more animals than birds in a pet shop.
- The number of birds and animals is equal.
- The number of legs is 4/5 of the original.
To find: The number of birds and animals.
Solution:
Let's assume the number of birds as 'x'.
- According to the first condition, the number of animals will be 'x+11'.
- According to the second condition, the number of animals and birds are equal. Therefore, the number of animals will also be 'x'.
Now, let's calculate the number of legs in the original scenario:
- Each bird has 2 legs.
- Each animal has 4 legs.
- Therefore, the total number of legs in the original scenario will be (2x + 4(x+11)) = (6x+44).
According to the third condition, the number of legs in the new scenario is 4/5 of the original:
- Therefore, the total number of legs in the new scenario will be (4/5)*(6x+44) = (24/5)x + 35.2.
Equating the two expressions for the total number of legs, we get:
(6x+44) = (24/5)x + 35.2
Solving for 'x', we get:
x = 11
Therefore, the number of birds is 'x' = 11 and the number of animals is 'x+11' = 22.
Hence, option 'C' is the correct answer.
