fresh fruit contains 68% water and dry fruit contains 20% water.how much dry fruit can be obtained fromfrom 100kg of fresh fruits.

Reply Like? Yes | No

(6 years ago)

Let say pulp is a content in fruit without any water.
Remove water% to get pulp percentage.
Fresh Fruit has (100-68)% = 32% of pulp
Dry fruit has (100-20)% = 80% of pulp
100 kg of fresh fruit has 100*32% =32 kg of pulp
Mass of dry fruit = (Pulp percentage in 100 kg of fresh fruit)/(Pulp percentage in dry fruit)
M= 32/(80%)
M = 40 kg.

The average of a list of 6 numbers is 20. If we remove one of the numbers, the average of the remaining numbers is 15. What is the number that was removed?

Reply Like? Yes | No

(6 years ago)

6*20-5*15=120-75=45

Like? Yes (2) | No

(6 years ago)

Let me answer this question first in a conventional way.
Sum of all the numbers = 6*20 = 120
Sum after remaining one number = 5*15 =75
So the number to be removed is 120-75 = 45
Ans : 45

Another approach is
After removing one number the average is reduced by 5
And also we are removing one number.
So the number is (Updated average)-(Change in average)*(Number of terms)= 15-(-5)*6 = 45.

A and B are running around a circular track of length 120 meters with speeds 12 m/s and 6 m/s in
the same direction. When will they meet for the first time? Answer

Reply Like? Yes | No

(6 years ago)

Let's assume both A and B start at the same point and same time.
The relative velocity of A with respect to B is 12-6 = 6 m/s.
This indicates for every second, A will be ahead of B by 6 metres.
So to meet B again, A has to cover a distance of 120 m (length of the track).
Time taken = 120/6 = 20 seconds

Ans: 20 Seconds.
