Question

how x and y are co-prime? pls explain clearly...​

Answer 1

Step-by-step explanation:

Co primes are the numbers whose common factor is only 1. Here they are asking you to find the 15 as the sum of any 2 co prime numbers. But in this only option c which is 4 and 11 is correct because when we find the common factors of 4 and 11 we get only 1

Answer 2

Step-by-step explanation:

Co-prime numbers are the numbers whose common factor is only 1.

so, what they have given in the answer means,

the value of x and y is co prime somehow u will find ok. now we can think that how many such pairs are possible. the x and y can 7 and 8 or even 4 and 11 etc.

if u find such possible numbers, then u must find how many pairs.

so the answer will be come.

And one more thing if u add x and y u get 15 right !?!?!!

I think that in question x and y are co primes they may given and if we add xa nd y we get 15

therefore the x and y values may be numbers between 15, and they are co primes. that's why u get 4 such pairs.
