thanks!

Long piece plus short piece plus pipe = 653. Long piece plus pipe = 533. So from here, find short piece. After that use the info given to find the other piece of rope i.e. longer piece. Once u know the length of the ropes, plus into the first mathematical statement and you get an equation. The pipe can be found by subtracting llength of ong piece and short piece from 653.

Thank a lot . Just one doubt..that 80% mentioned is not used anywhere??

It is. Look at 2nd model. 4u to 1u is 80% to total

Thank u.

Thank you .

Thank you Wahidah Khan. All the best to your kid too.

thk you everyone.

thank you #xavier

You are most welcome Perhaps someone can prove that 7^10 - 5^10 is divisible by 11, because I have no inkling how barring the use of an electronic calculator.

Er..... why does ending with "4" means it is not divisible by 7? O.o

If you look at the table in the picture I had posted for this question, only numbers that has 1, 3, 7 and 9 in the ones place for indices of base 7 can be divisible by 7. 4 is not in the table.

Yah that means that a number ending with "4" can't be an indices of 7.... But it doesn't mean that it cannot be divisible by 7 right...?

I see your point.

And what do you reckon?

No idea atm too.... >.<

Okay, since 7^10 is divisible by 7, and 5^10 is not, 7^10 - 5^10 cannot be divisible by 7. How is that?

Thanks for pointing out the lapse. I hope the last reasoning covers it.

Zhong Shu Hao deserves special mention for pointing out a lapse which is now addressed.
