x = amount of milk bars Mark bought at first
x-5 = the amount left after he eats 5 milk bars
(x-5)/3 = divide the previous result into 3 equal shares.
Mary gets one share plus 6 more milk bars
So she gets the (x-5)/3 plus another 6
I.e. (x-5)/3 + 6
Set this equal to 14 and isolate x
(x-5)/3 + 6 = 14
(x-5)/3 = 14-6
(x-5)/3 = 8
x-5 = 3*8
x-5 = 24
x = 24+5
x = 29
Mark started with 29 bars.
He eats 5 of them, so he has 29-5 = 24 left
That 24 is split 3 equal ways to get 24/3 = 8 bars per share.
Mary gets 8 bars plus another 6 to get 8+6 = 14.
We have confirmed the answer.
Answer: 29 milk bars.

The other tutor misread the problem. The 14 milk bars is the number Mark was left with -- not the number he gave to Mary.
x = original number of milk bars
x-5 = number after he ate 5
(x-5)/3 = one share
(x-5)/3+6 = number he gave to Mary
The number he is left with (14) is the original number, minus the 5 he ate, minus the number he gave to Mary:
ANSWER: He started with 35 milk bars
CHECK:
start with 35; eat 5; 30 left
30 divided into 3 equal shares is 10 for each share
number he gave to Mary was one share (10) plus 6 more = 16
number he has left at the end: 30-16 = 14

After reading your post, I have a question:
Is Mark " he " or " she " ?
If Mark is " he ", then WHO IS " she " at the first appearance of this word in the post ?
And since I asked, who is " she " at the first appearance, it is logical to ask, who is " she " at the second appearance ?
Without clarifying these fundamental issues, the problem cannot be solved.
The " problems " formulated so carelessly,
are good only to throw them to the closest garbage bin.
Waste of time.

When I criticize your formulation, you should not resent me.
Educated and intelligent people do not take offence in such cases.
In opposite, you should be grateful to me for my teaching.
It is a fortune for you that I captured your mistake and it did not go farther than this place.
