Question

A castle under siege has enough food for 300 men for 90 days. (Level 6) After 40 days, 150 men have left the castle.

Answer 1

Answer:

45 days

Step-by-step explanation:

300 men  = 90 days

the percentage of food consumed by one man

= ( 90 / 300 ) * 100

= 30%  = 0.3

After 40 days

150 men remain to consume at 30%

determine the number of days the remaining food will last ( x )

= x / 150 = 0.3

therefore ; X = 150 * 0.3 = 45 days
