It is 533.33http://www.puzzle.dse.nl/math/bananas_us.htmlrefer to the link...bohot bada solution hai...
Yaar isse zada to mere solution me are h banana
@scrabbler said:
I feel 0 to 4 but not able to prove.regardsscrabbler
try for values. it works
like equilateral consider karo, 111
then scalene 123
then isosceles 121...
0 to 4 hi aa rha h sab mein.. :)

So finally, 2000/3 = 666.66 Ab yaha kya kia maine?? Explain me what I did!

Haan woh kiya, but none of these ka option hai to doubt hota hai.

I also tried one other thing - (a+b+c)(b+c-a) can be expanded and rearranged to (b+c)^2 - a^2

Now one extreme case is a is close to zero in which case b and c must be almost equal (as b-c

Idhar how did you get 2000/3? Should be 1000/3

Aagewaala bhi aisa hi change hoga...

Nai..wo bananas left hai.. 1000/3 khalie so left = 1000 - 1000/3 = 2000/3 na?
@scrabbler Waise I just got to know that the camel eats 1 banana per KM, not necessarily after every 1 KM! AIMCAT question

And pray how will he then get back to the start? Teleport banana padega...

He has to carry 1000/3 back with him :P

Nai, Actually The question mentions that the camel eats 1 banana per KM, while carrying the bananas islie I did like this :P

Abdullah, a trader had 3000 bananas with him and he had to take them to a market 1000 km away on his only camel, which can carry a maximum of 1000 bananas at a time. Unfortunately, the camel eats one banana for every 1 km, or a part thereof, that it travels while carrying the bananas. What is the maximum number of bananas that Abdullah can take to the market?

:P Let's just leave this question

Somehow the thing ate half my solution when I posted 😞 Continued below...

...as b-c > a and hence putting a tends to 0, b tends to c, the value tends to 4 b^2 = 4bc so g = 4.

Also in the other extreme, the max value of a is almost = b+c so puttng that a tends to (b+c), (b+c)^2 - a^2 tends to 0. Hence g = 0 lower limit.

Then in 1000/3km he will eat 334 not 333.33, since it says part thereof. Playing with words is puerile :P

Ohhhhh..to ye meaning hai part thereof ka! Mujhe samajh ni aya tha to maine ignore kardia tha word ko! Thanks for mentioning though!

find the number of terms in the expression (a+b+c+d)^20

1671
1771
1717
7171
