If two pipes function simultaneously the reservoir is filled in 12hrs.one pipe fills the reservoir 10hrs faster than the other. How many hours does the faster pipe take to fill the reservoir?

Reply Like? Yes | No

Devendra Marghade 7 years ago

20 hours

Let slower pipe takes x hours, then faster pipe takes (x-10) hours.
Part filled in 1 hour=1/x + 1/(x-10) =1/12
=> (2x-10)*12 = x(x-10)
=> x^2 - 34x + 120 = 0
=> (x-4) (x-30) = 0
So x=4 or 30
As faster pipe takes 10 hrs. less than the slower pipe, the value of x must be 30.
Hence faster pipe takes 20 hours.

Reply Like? Yes | No

Chivaraman N 7 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

G.S.Kantharao 7 years ago

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

Like? Yes (2) | No

Chivaraman N 7 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

Chivaraman N 7 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.
