What is the weight of dry mango that can be obtained from 20 kg of Fresh Mango?
(1) Weight of dry mango to weight of water is 1:9.
(2) Fresh Mango contains 70% water by weight whereas dry mango contains 10% water by weight.

I've checked and there is a typo in Statement (1). Sorry about that.

(1) is INSUFF and bad wording.

(2) is as you guys proved below.

(D) for me :)

Stat 1

Weight of Fresh mango = Weight of Dried mango + Weight of water = 20
And
Weight of water = 9 * Weight of Dried mango

SUFF.

Stat 2

0,7 * Weight of Fresh mango = Weight of Dried mango + 0,6 * Weight of Fresh mango

with

Weight of Fresh mango = 20

SUFF.

At least I can try ;) :)

Well, to me there are 2 indicators:
> We are speaking of a process that consists of separating 2 elements from one. Fresh Mangoes give water + Dried Mangoes. Thus, logically, the description done in statment 1 is about these 2 elements.
> We cannot conclude with a ratio of 1:9 on something dried that it's the water present in the dried mango. It's simply too much.

Both indicators brought me the conclusion that we are speaking about the water gone from the fresh mangoes :)

This is a great question but statement 1 is poorly written.

Maybe writing stmt 1 as something like this makes more sense:

1) Weight of dry mango to weight of water extracted from drying the mango is 1:9

Just curious, what is the source of this problem?
