Answer:
Given that food was sufficient for 2000 people for 54 days
Hence, after 15 days, the remaining food was sufficient for 2000 people for 39 days (∵ 54 - 15 = 39)
Let
x
number of people came after 15 days.
Then, total number of people after 15 days
=
(
2000
+
x
)
Then, the remaining food was sufficient for
(
2000
+
x
)
people for 20 days
More men, Less days (Indirect Proportion)
(men) 2000 :
(
2000
+
x
)
:: 20 : 39
