a) 40 days                b) 50 days                c) 90 days                    d) 80 days



Solution:

We arrange data as below;

Now term at tail of arrow will be up in fraction, while term at head of arrow will be down in fraction!

we write in equation form as below;

\frac{1600}{1200}= \frac{x}{60}

Leave ‘x’ on one side and shift other terms to other side;

\Rightarrow x=\frac{1600}{1200}\times 60

\Rightarrow x=80

So food and amnesties will be sufficient for 80 days
