35 days they sustain

Answer 2

$\text{Originally the Garrison has provision of 30 days for 120 men} \\ \text{after end of 5 days provision of 25 days is left}\\ \text{provision for 120 men will last for 25 days, so if 5 more men join} \: \\ \text{product of original number of men and 25 days} = \text{product of 125 number and new number of days}\\ \text{let the number of days which provision will last now be x}\\ \implies x\times 125 = 120 \times 25\\ \implies x = \frac{120 \times 25}{125}\\ \implies x = \frac{120}{5}\\ \implies x = 24\\ \text{Hence, after 5 days the provision will last 24 days for 125 men} \:$
