Fun Number Riddle: Find the Sum of the Weights


look at the given equations in the riddle and find the value of ?.

in the picture, you will see dog, cat and rabbit faces representing their weights.

From all the given information, find out the sum of their weights.

 

Answer: 27 kg.

Explanation:

To simplify, let’s write the pictorial equation in text form

let’s assume the following;

the dog’s weight be d;

the cat’s weight be c &

the rabbit’s weight be r

From the given information we can write the following equations;

c +d = 24

c + r = 10

d + r = 20

We have to find the addition of the weights of all the three animals.

Let’s add the above 3 equations;

c +d = 24
c + r = 10
d + r = 20
2c + 2d +2r = 54

We can solve the above equation as follows;

2 (c + d + r) = 54

Therefore;

c + d + r = 54/2 = 27

So the addition of the weights of all the 3 animals is c + d + r = 27 kg.
