Question

a garden has 3000 trees, 15%of these are orange trees, 19%of these are lemon and rest are mango trees.find the number of mango trees

Answer 1

TO FIND THE ANSWER AT 1ST WE HAVE TO FIND THE NO. OF ORANGE TREES AND THE NO. OF LEMON TREES. THEN WE HAVE TO ADD THEM. AND AT LAST WE HAVE TO SUBTRACT IT FROM 3000.

=3000-{15 PERCENT OF 3000+ 19 PERCENT OF 3000}

=3000-[450+570]

=3000-1020

=1980
