Is x less than 20 ?
1. The sum of x and y is less than 20.
2. y is less than 20.
Statement 1x+y<20
say x=5, y=14, sum is 19. so x+y < 20. Also x is less than 20.
Now take x=25, y=-16, sum is 9. so x+y < 20.
BUT x is
more than 20.
So not sufficient
Statement 2This statement does not say anything about x. Clearly Not sufficient.
Combining Statements 1 and 2Our above examples will suit the purpose, as in both cases y is less than 20.
say x=5, y=14, sum is 19. so x+y < 20. Also y is less than 20. Here x is less than 20
Now take x=25, y=-16, sum is 9. so x+y < 20. Also y < 20.
BUT x is
more than 20.
So even after combining Not sufficient.
(E) is the answer.
