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.

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.

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.

@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.
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.

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.

Shouldn't it be 200*120/50?

Here; Remaining children are 50 and this is 25% of 200, so 25% of men is 30.

120/200 = men : children.
15men = 25 children.
200-150 = 50(consumed).
(25x2)Children = 50(remaning).
:.(15x2)men = 30(remaining).
15men = 25 children.
200-150 = 50(consumed).
(25x2)Children = 50(remaning).
:.(15x2)men = 30(remaining).

200 : 120 = 3 : 5.
Then remaining 50 child = 50 * 3/5 = 30.
Then remaining 50 child = 50 * 3/5 = 30.
