Please note that last digit is given as 6.
Multiply it by 4 , we get 24.
It means digit at unit place for new number ( after placing unit digit at front place of original number ) is 4 and hence 4 will be at tens place of original number.
Multiply 4 with 4 , we get 16 and add 2 ( carry from first product) to get 18. So 8 is next digit.
Repeat this process till we get 6 in final number (product).

A man has 1044 candles.after burning,he can make a new candle from 9 stubs left behind.find the maximum number of candles that can made?

Reply Like? Yes | No

(6 years ago)

out of 1044 candles we can make 1044/9 i.e. 116 candles.
then out of 116 candles we can make 116/9 i.e 12 candles and 8 stubs left.
now out of 12 candles we can have 12 stubs and 8 above stubs so out of 20 stubs we can make 20/9 i.e. 2 candles. and 2 stubs remaining.
at last we have 2 stubs of above candle and remaining 2 stubs i.e 4 stubs .which cant make a candle.

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

(6 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.

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%)

(6 years ago)

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

(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.

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
