Question

If 5 horses eat 18 quintals oo oats in 9 days, how long at the same rate will 66 quintals last for 15 horses?

Answer 1

Answer:

11 days

Step-by-step explanation:

for the first case....

we can say for one horse value

which is

x=18/(9*5)

then for 15 horses and 66 quintals

y= 66/15x

x is the value of first case

y is the no of days (which we have to find)

so now,

y= (66*5*9) / (15*18)

y= 11 days

Answer 2

Given : 5 horses eat 18 quintals of oats in 9 days.

To find : How long at the same rate will 66 quintals last for 15 horses?

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the required number of days)

Here, we will be using general arithmetic method.

So,

For 5 horses 18 quintals last for = 9 days

For 1 horse 18 quintals last for = (9×5) days

For 1 horse 1 quintal lasts for = (9 × 5)/18 days

For 15 horses 1 quintal lasts for = (9×5)/(18×15) days

For 15 horses 66 quintals lasts for = (9×5×66)/(18×15) = 11 days

(This will be considered as the final result of the given mathematical problem.)

Hence, at the same rate will 66 quintals last for 11 days.
