The solution to this type of question can be found from observation.
Given that 150 children out of 200 children have taken the meal.i.e, 3/4th of children have been supplied by the meal. So 1/4 the of the children have to be supplied with the remaining meal.
As it is given that 120 men = 200 children.
Therefore the remaining meal must be supplied to 1/4th of 120 men viz.,30 men.

@Hemanth proportionality is clearly visible, more men catered imply more children catered there is direct proportionality.
i.e
120 : x :: 200 : 150.
200 * x = 150 * 120.
x = 90 so, 150 children are equivalent to 90 men, remaning food is for men = 120 - 90 = 30.

1 men can have food = 1/120.
1 child can have food = 1/200.
150 child can have food = 150*1/200 = 150/200.
Left food = 1-150/200 = 50/200.
1/120 portion of the food taken by = 1 men.
50/200 portion of the food taken by = 1/(1/120)*(5/20) = 30.
1 child can have food = 1/200.
150 child can have food = 150*1/200 = 150/200.
Left food = 1-150/200 = 50/200.
1/120 portion of the food taken by = 1 men.
50/200 portion of the food taken by = 1/(1/120)*(5/20) = 30.

Ratio for 120 and 200 = 3:5.
Then, 150/5 = 30.
So 1 part = 30,
Then 3 parts for men is 3*30 = 90 and 5 parts for children is 5*30 = 150.
So 90 men = 150 children.
Remaining men = 30.
Then, 150/5 = 30.
So 1 part = 30,
Then 3 parts for men is 3*30 = 90 and 5 parts for children is 5*30 = 150.
So 90 men = 150 children.
Remaining men = 30.

200 children= 120 men ---- (1).
50 children= 30 men ---- (2).
150 children takes the food, so there is food for only 50 children
from 2.
30 men will be catered the remaining meal.
50 children= 30 men ---- (2).

Let man = m and children = y.
Then meal of 120m = 200c.
Meal of 1m = (200/120)c.
1m = 5/3c.
i.e (5/3)c = 1m.
5c = 3m.
1c = (3/5) m.
50c = (3/5*50) m.
50c = 30m.
Then meal of 120m = 200c.
Meal of 1m = (200/120)c.
1m = 5/3c.
i.e (5/3)c = 1m.
5c = 3m.
1c = (3/5) m.
50c = (3/5*50) m.
50c = 30m.

It's so simple here 120:200 is nothing but 3:5 means 3 men =5 children means 1 child=3/5 men and remaining 50 children=50* (3/5) =30 and its the answer it is easy.

@ seranya--
its given that
200 children= 120 men
So 1 child= 120/200 men
hence, 150 child=120/200*150= 90 men.
so meal will be available for 120-90= 30 men
its given that
200 children= 120 men
So 1 child= 120/200 men
hence, 150 child=120/200*150= 90 men.
so meal will be available for 120-90= 30 men

Ya its eazy....
200 children = 120 men
1 children = 120/200 men
we have food remaining for 50 children
So, 50 children = 120/200*50 = 30 men
200 children = 120 men
1 children = 120/200 men
we have food remaining for 50 children
So, 50 children = 120/200*50 = 30 men

200c = 120m.
=> 100c = 60m.
=>50c = 30m.
Out of 200c, 150c have taken meal.
So, remaining food is for 50c which is equal to 30m.
=> 100c = 60m.
=>50c = 30m.
Out of 200c, 150c have taken meal.
So, remaining food is for 50c which is equal to 30m.
