Hi,
Just my 2 cents
The problem is not at all unqiue, its only the values of simultnaeous equation can result to a different path
1. 15x +29y=440
I cannot just try different and "*unique values*" to solve the equation in 2 min, I have
I will use the concept 2 variables and hence need 2 equation and would go to stmt 2
2. x=y
2 alone cannot also solve
hence combine
44x=440
x=10
hence, it wuld be C for me in 2 min in exam ( I guess Cramya requested to recheck OA based on this logic)
But, we should thank logitech to provide a question which now tells us that there could be few simualtenous equations where we should atleast check if for few unique values of x and y , equation may be satisifed
I would just rem in my mind about his simulatenous equation to add one more to my credit
However, if we can get an expert clue as to how we can judge just looking at the simulatenous equation that there could be unique values of it or in min calculation have the solution
Just my 2 cents

This is what I liked about this question and wanted to share with rest of you.iamcste wrote:Hi,

Because whenever you see a weird looking prime number, such as 29, you need to think about this question!
