Answer 1

Answer:

5 horses along with 3 elephants will finish the same task twice in 10 hours.

Answer 2

There will be 5 horses along with 3 elephants to finish the same task twice in 10 hours.

Step-by-step explanation:

Since we have given that

Number of horses = 5

Number of elephants = 4

Time = 4 hours

2 elephants can complete the same task in 10 hours.

So, using "Time and work", it becomes,

$(5H+4E)\times 4=2E\times 10\\\\2(5H+4E)=10E\\\\10H+8E=10E\\\\10H=2E\\\\5H=E$

Now, we need to find the number of horses with 3 elephants to finish the same task twice in 10 hours.

$2E\times 10=\dfrac{(xH+3E)\times 10}{2}\\\\4E\times 10=(xH+3E)\times 10\\\\4E=xH+3E\\\\4E-3E=xH\\\\E=xH\\\\5H=xH\\\\x=5$

Hence, there will be 5 horses along with 3 elephants to finish the same task twice in 10 hours.
