Given that x and y are estimated as x = 13 +or-0.5 and y = +or-0.2. Calculate the maximum possible value of
a) x -y
b) x + y
c) xy
d) $\frac{x}{y}$

Answers

a) x = 13 +or-0.5 and

y = 1.9 +or-0.2

Maximum possible values are

a) x-y

= max.x-min.y
= 13.5 - 1.7

= 11.8

b) x + y

= max.x + max.y

= 13.5 + 2.1

= 15.6

c) xy

= max.x x max.y

= 13.5 x 2.1

= 28.35

d) $\frac{x}{y}$ = $\frac{maximum\;x}{Minimum\;y}$

= $\frac{13.5}{1.7}$

= 7.941
