Question

35+12=12 ,54+17=14 ,84+21=?

Answer 1

I think your answer is 22 .but not sure.

Answer 2

Answer:

Our answer is 21

Step-by-step explanation:

Given that

35 + 12 = 12

54 + 17 = 14

We have to find that

84 + 21 = ?

Lets take the example of

35 + 12 = 12

Now among 3 and 1 which are first digits of two numbers 1 is smallest so we placed it at first place of answer, similarly among 5 and 2 which are second digits of two numbers 2 is smallest so we placed it at second place of answer, and this way we get our answer 12

Lets take the example of

54 + 17 = 14

Now among 5 and 1 which are first digits of two numbers 1 is smallest so we placed it at first place of answer, similarly among 4 and 7 which are second digits of two numbers 4 is smallest so we placed it at second place of answer, and this way we get our answer 14

Now lets take our last expression

84 + 21 = ?

Now among 8 and 2 which are first digits of two numbers 2 is smallest so we placed it at first place of answer, similarly among 4 and 1 which are second digits of two numbers 1 is smallest so we placed it at second place of answer, and this way we get our answer 21

So, our answer is 21
