What is the minimum value of (a+b+c) when its given that (a^2) *(b^3)*c= 256/27 and a,b,c are all real positive numbers? (1)5 (2)3 (3) 6 (4) 4 (5) none of these

4?
(a/2+a/2+b/3+b/3+b/3+c)/6=(a^2/4*b^3/27*c)^1/6=(256/27*1/4*1/27)^1/6=(2/3)
--->a+b+c=6*2/3=4??
in hw many ways a cricketer can scor 200 using fours & sixes.?

(4) 4.

Must be 4
If xΔ(y +1) = yΔ(x +1),xΔ x = 1 and (x − y)Δ(x + y) = xΔ y, then what is the value of 1001Δ1?
Δ is an operator

6x+4y =200
3x+2y=100
x=2k
6k
k=0-16
17 ways
EDITED-> missed the case when k=0 :banghead:
Thanx @Ibanez

@The_Loser said:in hw many ways a cricketer can scor 200 using fours & sixes.?
a=# of 4's
b=# of 6's
4a+6b=200
2a+3b=100
b must be even, so let b=2k
2a+6k=100
a+3k=50
a=2,5,8,.................,47,50
total 17 values.....
b=# of 6's
4a+6b=200
2a+3b=100
b must be even, so let b=2k
2a+6k=100
a+3k=50
a=2,5,8,.................,47,50

@The_Loser said:in hw many ways a cricketer can scor 200 using fours & sixes.?
2x+3y=100
50 0
47 2 ....
x=>50 ,47...0 => 51/3+1 = 18 But x=0 is not possible
So ans=17
@techsurge said:@The_Loser6x+4y =2003x+2y=100x=2k6kk=1-1616 ways
3x+2y=100
y will take values 2,5,8..... 50
so total (50-2)/3 +1 = 17 values :)
y will take values 2,5,8..... 50
so total (50-2)/3 +1 = 17 values :)

My take - 1
Rohan is asked to figure out the marks scored by Sunil in three different subjects with the help of
certain clues. He is told that the product of the marks obtained by Sunil is 72 and the sum of the
marks obtained by Sunil is equal to the Rohan €™s current age (in completed years). Rohan could not
answer the question with this information. When he was also told that Sunil got the highest marks
in Physics among the three subjects, he immediately answered the question correctly. What is the
sum of the marks scored by Sunil in the two subjects other than Physics?
