Anand packs 304 marbles into packets of 9 or 11 so that no marble is left. Anand wants to maximize the number of bags with 9 marbles. How many bags does he need if there should be atleast one bag with 11 marbles
a. 33
b. 32
c. 31
d. 30
Read Solution (Total 6)
-
- 9X+11Y=304
for this ques because equation tells there are num of 9 bags and11 bags that contain x and y num of marbles respectively.
here y>1
so for l values from 1,2.....n equations satisfies at y=8 and x=24
9*24+11*8=304 - 9 years agoHelpfull: Yes(8) No(3)
- Firstly, divide total marbles by 9 i.e.,(304/9)=33(Remainder 7).
Now, decrease bags of 9 n add '9' value to remainder and the sum shud b divided by 11
i.e.,
24 of 9' bags and 8 of 11 bags
24*9+8*11=304 - 9 years agoHelpfull: Yes(2) No(3)
- Ans : 32
let the number of packets with 9 marbles be x
and the number of marbles with 11 marbles is y
then 9x+11y = 304
one general solution for this equation is (24,8)
others solutions will get by decreasing x by 11 and by increasing y by 9 ex:(13,17)
hence the answr is 32 - 9 years agoHelpfull: Yes(2) No(2)
- 32 is the answer.
11x+9y=304
x=304-9y/11
