Ji's overall percentage is #81.2%#

Explanation:

As marks allotted to practical exam are #60%# and allotted to theory exam are #40%#,

assume marks allotted to practical exam are #60# and allotted to theory exam are #40# and total is #100#.

Ji scores #84%# in practical exams i.e. #(60xx84)/100=50.4#

and scores #77%# in theory exam i.e. #(40xx77)/100=30.8#

i.e. a total of #50.4+30.8=81.2# out of #100#

Hence overall percentage is #81.2%#
