A. 16 B. 17 C. 18 D. 19 E. 20 Given, x<y and y < 10 we are asked to determine the greatest value of x + y . y ( max) = 9.9999 x ( max) = 9.9998 x + y = 19 ( max) Thus the best answer is D.

I think it will be D. Take x = 9.2, y= 9.8, then x + y = 19. Since they have asked for greatest possible integer value and they have not mentioned x and y are integers.

A. 16 B. 17 C. 18 D. 19 E. 20 selim, always be care ful to read wordings.. we are looking for max integer value of x and y and x and y need not be integers so take the max possible value if x<y<10 \(9.9999998<9.999999<10\) so both x and y can be just near 10 but less than 10.. so x+y will be near 20 but slightly less than that so answer 19

A. 16 B. 17 C. 18 D. 19 E. 20 Given x<y<10. Max(x+y)=max(x)+max(y)=9.99+9.98=19.97 But we are asked the greatest possible integer value of x + y, hence Max(x+y)=19 Ans.(D)

A. 16 B. 17 C. 18 D. 19 E. 20 We need integer value possible for Max (x + y) Given, x < y < 10, hence Max (y) = 9.9 & Max (x) = 9.1, considering only one decimal place for simplicity We get integer value possible for Max (x + y) = 9.9 + 9.1 = 19 Max (x + y) cannot be 20, as both x & y are less than 10. Hence the only integer value for Max (x + y) below 20, is 19. Answer D. Thanks, GyM

A. 16 B. 17 C. 18 D. 19 E. 20 We need x + y as integer but x and y can be fractions. With this in mind, Say x = 9.8 , y = 9.9 as x < y x + y = 19.70 = 19 So, D
