no. of men remaining =210-60=150 men
the food Will last=2/7 multiply 150 men

3mins

Answer 2

Answer:

70 days

Step-by-step explanation:

The remaining food would last for 60-10=50 days.

Now we are given that 60 men left.

Number of remaining men= 210-60 = 150

For 210 men food last for 60 days.

Let x be the no. of days the remaining food last for 150 men

ATQ

$210:150=x:50$

$150 \times x=210 \times 50$

$x=70$

Hence the remaining food will last for 70 days
