Question:
ek chhatrawas me 300 students ke liye 45 dino ka ration hai. 31 din bad 195 student chale gaye . shesh ration, shesh student ke liye kitane din chalega
Answer:
Student*Day = 300*45 = 13500
After 31 days, 195 students has gone.
So, 31*300 = 9300
Now remaining = 13500 - 9300 = 4200
Student *day = 4200
=> (300 - 195)*day = 4200
=> 105*day = 4200
=> day = 4200/105
=> day = 42
So, number of days food is available for remaining students is 42
