1.	a+b/a=cIn the equation above, if "a" is negative and "b" ispositive, which of the following must be true?A) c > 1B) c = 1C) c = −1D) c < −1
Answer» a is always -ve and b/a is +ve/-ve => -ve so, -ve +(-ve) = -ve = c also, when b and a will tend to approach →0then the least value of b/a will become -1... so, the expression a+b/a will always be < -1 so c < -1 option D.

a+b/a=cIn the equation above, if "a" is negative and "b" ispositive, which of the following must be true?A) c > 1B) c = 1C) c = −1D) c < −1

Answer»

a is always -ve and b/a is +ve/-ve => -ve

so, -ve +(-ve) = -ve = c

also, when b and a will tend to approach →0then the least value of b/a will become -1... so, the expression a+b/a will always be < -1 so c < -1

option D.
