Expert Answer
Let x soldiers join the the camp after 17 days
The quantity of food remains the same
50 x 2200
Food consumed by 2200 soldiers in 17 days is 2200 x 17
remaining food
50 x 2200- 17x 2200
=33 x 2200
NOw x soldiers joined the cam due to which the food has been consumed in 20 days only
33 x 2200 = 20 x (2200 +x)
x=1430
