9c3 = no. of ways to select 3 dogs out of 9
3c1 = no. of ways of selecting one sledge out of 3
Therefore total no. of ways to apply a team of three dogs in first sledge
= 9c3* 3c1
for second set of dogs
= 6c3*2c1
for third set
= 3c3*1c1

Therefore total ways = 9c3*3c1+6c3*2c1+ 3c3*1c1

10x/(x+y) + 20y/(x+y) = K


(10x+20y)/(x+y) =K

(10(x+y) + 10y)/(x+y) = k

10 + 10*y/(x+y) = K

Now, second term on LHS is less than 10 therefore , 30 is out
y/(x+y) can't be less than 1/2 as x<y therefore only option left is 18.
