Question

days When wheat is Rs 3.90 per kg. 60 men can be fed for 15 days at a certain cost. how many men can be fed for 45 days at the same cost, when wheat is Rs 3 per kg?​

Answer 1

Step-by-step explanation:

Consider x kg is needed to feed 60 men for 15 days.

Then x/60 kgs is needed to feed 1 man for 15 days.

Then x/20 kgs is needed to feed 1 man for 45 days.

Previously cost of the rice bought was Rs 3.9x

Now, quantity of rice that can be bought with same cost is 3.9x/3 = 1.3x

x/20 kgs is needed for 45 days by 1 man

x kgs is needed for 45 days by 20 men.

1.3x kgs is needed for 45 days by 26 men.

Hence the answer is 26 men.

Answer 2

Step-by-step explanation:

∆.Question:----------->

¶¶•days When wheat is Rs 3.90 per kg. 60 men can be fed for 15 days at a certain cost. how many men can be fed for 45 days at the same cost, when wheat is Rs 3 per kg?•¶¶

Solution:----------------->

• suppose it is 1000kg wheat from which 60 men can be fed for 15 days.

---amount of wheat which is consumed by one day

=1000/(15)=200/3kg

°amount of wheat which is consumed by one men in one day

=1000/(60×15)= 10/9kg

cost of 1000kg wheat= 1000×3.9

= 3900

its mean is, they use 3900 Rs for fed 60 men 15 days

°now,

when wheat rate is 3rs/kg

•amount of wheat which will be get in 3900

=3900/3= 1300kg

∆now,

amount of wheat consumed in 45 days

=45×200/3= 3000kg

if we reduce the number of consumer then we

would fed for 45days
