let f m n 45 m 36 n where m n ve or -ve int what is minimum value for

ans:9
if we put m=1,n=-1
then 45-36=9
the first no should be given positive value,since the minimum positive value is being asked

f=45*m+36*n
f=9(5*m+4*n)
f/9=5*m+4*n

for integer values of n and m f should be in multiples of 9.
ie, minimum possible value of f is 9.

if both m and n are large negative nos..then we will get least value(more negative value)...??anyone please post correct solution

go by option.

They have asked the"minimum positive value". So large negative values wont come under that condition. So i suppose 9 is the answer.

I think the ans could be 0 as well..... taking the LCM of 45,36 ie 180 and put m=4,n=5 that will results f(4,5)=180-180=0......

guys 0 is not a positive number.So 9 is the correct answer.

by options we can solve
9 years agoHelpfull: Yes(1) No(0)
d=gcd(45,36)
d=gcd(32∗5,22∗32)
d=32
d=9

the question is saying what is the minimum value of f(m,n), not m and n!
minimum value of f(m,n)=0

as we can substitute m=4 and n=-5
45*(4)+36*(-5)
180-180=0

What so many wrong ques?? tcs

for larger negative values of m,n doesnt make f(m,n) negative ,,,, i think they should say min positive integer value
9 years agoHelpfull: Yes(0) No(0)
ans=9
f(m,n)=45*m+36*n

let f(m,n)=45m+36n where m & n(+ve or -ve int)what is minimum value for f(m,n) for all m,n(this may be achived for various values of m,n)
