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.

They are just asking how many people are equal to 50 children.
120:x = 200:50.
x = (120*50)/200 = 30.
120:x = 200:50.
x = (120*50)/200 = 30.

200 children = 120 men.
1 child = 120/200.
= 0.6.
Hence, 50 children - 0.6*50 = 30 men.
1 child = 120/200.
= 0.6.
Hence, 50 children - 0.6*50 = 30 men.

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.

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).

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

It's simple like this.
If 5 pens cost 25 Rs
1 pen cost?
25/5 = 5.
If 5 pens cost 25 Rs
1 pen cost?
25/5 = 5.

@ 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
