ANSWER EXPLANATIONS
 We can observe that . We need another to bring the total 1.
But instead of , the next term issued which is only half of it. This type
of error / shortfall occurs, no matter how many terms are added. As the number of terms increase, the sum which comes closer and closer to 1, always remains less than one.
Hence B.
 X < 0 means x is negative. hence x^{3} is also negative whereas x^{2} is positive. A positive number is always more than a negative number.
Hence B.
 ( x + y ) is any number between 1 and +1. Hence ( x + y ) can always be made of components x and y, such that x > y or x = y or x < y.
Hence D.
 y^{2} = 49 implies that y can be either +7 or even 7. Hence y can be equal to 7 or y can be less than 7. ( Since 7 < +7 )
Hence D.
 Again y^{2} = 49 implies that y = +7 or 7.
If y = +7 then 2y^{2} < 3y^{3}
If y = 7 then 2y^{2} being positive will be more than 3y^{3} which will be negative.
Hence D .
 If a > 0 and b < 0 then a  b will be effectively be the positive sum of the magnitudes of ' a ' and ' b ', whereas a + b will effectively be either a positive or negative difference of the magnitudes of ' a ' and ' b '.
Hence A.
