11% of 80 = (80*0.11) = 8.8
11% greater than 80 = 80 + 8.8 = 88.8

Answer is clearly A.

please can someone show me how x=91.

i get x=88.8

Maybe it's worded incorrectly? "X is 11% greater than 80" does not have the same value for X as "80 is 11% less than X"

Even then, though, the answer would only be 89.8

\(x = 80 + \frac{11}{100} * 80\)

x = 80 + 8.8

x = 88.8

Answer = A

x is 11 percent greater than 80, then
x = 80 * 1.11
x= 88.8
(A) is correct !
