Answer:
15 days
Step-by-step explanation:
/* Ration is for 75 students for 20 days */
/* Find total ration available */
Total Ration = 75 x 20 = 1500
/* Find the ration consumed by the 75 students in the 10 days */
Ration consumed = 10 x 75 = 750
/* Find the ration left after 10 days */
Ration remained = 1500 - 750 = 750
/* 25 students have left */
/* Find the number of students remain */
Number of students = 75 - 25 = 50
/* Now there are fewer students, the ration can last longer */
/* Find the number of days the ration can last for 50 students */
Number of days = 750 ÷ 50 = 15
Answer: The ration can last 15 days
