Question

Danish ate fiveseventh of oranges of his orange before lunch one seventh of his orange after lunch . How much orange did he eat in all

Answer 1

we know that Danish ate 5/7 of his orange before lunch,
we also know that Danish ate 1/7 of his orange after lunch
so total orange = orange eaten before lunch+ orange eaten after lunch
                          = 5/7 + 1/7
                         = 6/7
therefore, Danish ate 6/7th of his orange in total

Answer 2

No of oranges eaten = 5/7 + 1/7
=6/7
He ate 6/7th of his oranges
