Answers:
in recent times 17
she started beside 17
working the problem backwards - start at 25 pens, she bought 5 but we're doing it backwards so this time around
bought = subtract
give away = add
so we hold 25 pens - 5 = 20
gave away 3 means 20+3 = 23
bought 6 = 23-6=17
working it adjectives out you get 17(start) +6she bought= 17+6=23
23 give away 3 is 23-3=20
then bought 5 more =20+5=25
and within you have it ^^
17.
6-3+5=8
25-8=17
17+6-3+5=25
Use algebra:
x+6-3+5=25
x+8=25
x=25-8
x=17
Now verify.
Buys 6. (17+6=23)
Gives away 3. (23-3=20)
Bought 5. (20+5=25)
Just do the question surrounded by reverse.
She has 25 in the end, so pocket away the 5 she buys and she has 20.
Then if she gets the 3 pens she give out and has a total of 23 pens.
Finally take away the 6 she bought and you achieve 17 pens.
Therefore she started with 17 pens.
17
6 - 3 = 3
3 + 5 = 8
25 - 8 = 17 Source(s): Simple math
You said she "had" 25 pens but did not specify the point contained by time she had that. It could be before she bought or gave any pen at adjectives so I am inclined to say she had 25 pens. The answer might vary if you say she "has". Or not.
17
everyone else has already explained.
17
25-6-5-3
11
she started with 17 pens because 6-3=3, 3+5=8, 25-8=17 she have 17 pens to start with
idk 20
17. Take 25 (end result) and subtract how many she added [(6-3=3) and (5)]. So 25-3-5=17. To check your answer take 17 as how oodles she started with, add 6, subtract 3, then tag on 5. If you get 25, then it is correct.
do no man, but you mae many mistake.
