Answer:
The weight of watermelon at the end of the trip is <u>500 kg.</u>
Step-by-step explanation:
Given:
The weight of watermelons is 1000kg.
At the beginning of the trip watermelon is 99% of the weight:
99% of 1000kg
kg
Now, at the end of the trip it is 98% of weight. So, let kg of water has been evaporated. So, remaining weight of the watermelon is
.
If kg of water is removed, then the amount of water left is
.
As per question, water now weighs 98% of the total weight. So,
98% of () =
(Bringing like terms on one side)
Therefore, the weight of watermelon at the end of the trip is given as:
Weight = = 1000 - 500 = 500 kg
Therefore, the watermelon weighs 500 kg at the end of trip.
Answer:
Step-by-step explanation:
Given
i.e. 10 people
Required
Probability of being next to each other
First, we calculate the total possible arrangements (without any restriction)
If the three are to be next to each other,
First, we arrange the three
Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)
The arrangement is:
So, the total arrangement, when they have to be next to one another is:
The probability is:
Expand
Express as percentage
