Suyog,
I have something to say here. According to the prob -
7 * 5 * 3 * 2 * rygb = 147000
[Where r = no of red balls, y = no of yellow balls and accordingly]
so rygb = 700
From this point how can u get the value of r? And the other thing is - I am not getting your approach! Little more explanation ...
Correct me If I am wrong

147000 can be broken down into 7 * 7 * 5 * 5 * 5 * 3 * 2 * 2 * 2

(please note that there are no other combinations possible
with 7, 5, 3 and 2)

Given that red = 7 points, there must be 2 red beads

if you read the question carefully... It says the product of point values is 147000 so when i say....
147000 = 2 * 2 * 2 * 3 * 5 * 5 * 5 * 7 * 7
It means there are 3 blue, 1 green, 3 yellow and 2 red beads.
ans hence ans is 2
