Question

a Fort had provision for 175 men for 70 days after 10 days 25 men left the food how long would the provision last

Answer 1

The right answer of this question will be 70

175×70 = 175×10 + (175-25)×X
175×60 = 150× X
X = 70

Answer 2

Solution:-)
The remaining food would last=70-10=60

Again,

Number of remaining men =175-25=150


then.

150:175::60:x

150x=60*175

x=60*175/150


X=70


then,

70 Days



that's all
