In a survey carried out among 100 soldiers, the
investigation shows that 42 were shot on
head, 43 on arm, 32 on leg, 5 were shot on
head and arm, 8 on arm and leg and 6 on leg
and head. How many soldiers were shot; (i). all
three parts of the body.
Plz help
assuming all were shot somewhere,
(42+43+32) - (5+8+6) + x = 100
