Answer 1

plzz correct the wrong no. of mint

maybe it is 6 not o

if 6 mints are in green wrapped paper then

(1) sum of all mints/total no. of sweets

=6+4/20

=10/20

=1/2

(2) sum of toffee/total no. of sweets

=7+3/20

= 10/20

=1/2

(3) total no. of sweets wrapped in green paper

=7+6/20

=13/20
