Answer to brain teaser
To solve the equation, you need to start with the ducks. If you divide 21 by 3, you will get the value of one duck. This can help you with the second part of the math puzzle. If a duck and two orange birds make up the number 17, and the duck is 7, the value of one orange bird is 5. Similarly, you can find the value of the crow in the third part of the problem.
The answer to the final part of the problem is 25. Two orange birds (5 x 2 = 10), a crow (8) and a duck (7) add up to this number.
