Question

3. A garrison of 900 men had provisions for 50 days. After 8 days, a
reinforcement of 500 men arrived. For how many days will the food last
now?​

Answer 1

Answer:

m¹×d¹=m²×d²

900×50=(900+500)(8x)

45000=1400×8x

x~275

Answer 2

Answer:

Answer is 27 days.

Step-by-step explanation:

Let 1men eat 1 roti everyday.

So, 900 men eat 900 roti everyday.

Food available for them for 50 days

Hence roti available = 900×50=45000 roti.

And food was eaten for 8 days so 900×8=7200 roti were eaten.

So,roti left = 45,000-7200=37,800 roti.

500 men increased so total men now are 900+500= 1400 men.

So, 1400 men eat 37,800 roti in 37,800/1400 =27 days.
