Question

If X is a subset of A*B and n(A*B)=9 where X={ (x,y) :
4x+y=10,where x and y are whole numbers} , then what will be the
representation of the set A?

Dear Student ,
This must be a multiple choice question
And '*' must denotes binary operation
â€‹â€‹â€‹So,
the sollution is as follow :-

Thus , A*B must include {(0,10),(2,2),(1,6)}
So, A must include {0,1,2,6,10}

=> The option with values { 0,1,2,6,10 } in it must be
the answer
