In this my post, I will answer questions (a) and (b), ONLY.
a. Jog but does not eat healthily
This set "Jog but does not eat healthily" is the set of those who like jog (210 persons, given)
 the intersection of those who jog AND eat healthy (i.e. minus 97).
So, the ANSWER to question (a) is 210 - 97 = 113.
b. Eats healthily and plays badminton but does not jog.
This set "Eats healthily and plays badminton but does not jog" is the set of those who maintain a healthy eating habit
and play badminton (83 persons, given) the triple intersection of those who involve all three practices
(i.e. minus 52).
So, the ANSWER to question (b) is 83 - 52 = 31.

J = jog
B = play badminton
H = eat healthily
The categories below indicate which of the three things individuals do -- e.g., "BH" means plays badminton and eats healthily but does not jog.
JBH: 52 (given)
JB: 122 (given) - 52 = 60
JH: 97 (given) - 52 = 45
BH: 83 (given) - 52 = 31
J: 210 (given) - (60+45+52) = 53
B: 258 (given) - (60+31+52) = 115
H: 216 (given) - (45+31+52) = 88
ANSWERS:
a. Jog but does not eat healthily:
J + JB = 53+60 = 113
b. Eats healthily and plays badminton but does not jog:
BH = 31
c. Does not jog or eat healthily:
B = 115
