Hello all,
For yesterday's puzzle
Answer is 15.13 meter which in the provided options is approximated to 15.15 meter
So going forward, please don't bother for difference of 20 centimeter when the numbers in question is in meter!

Or else we will loose points the way I lost

Hope this comment helps for your future endurances

It's a tricky question Varun. Here you should remember as 0.08% is a whole number. That's why it is 2500
See let X be the number
x*8/10000=some whole number.
x=10000/8=2500

Thanks Kantha for explaining with logic, very much appreciate the time spent in explaining.

Team m4maths, we can improvise the result posted by admin, we see number 2 implicitly used in explanation which we can logically explain by saying that it helps in arriving at one of the solutions present in options.

Dear Admin
Please check your answer for yesterday's (i.e.8-3-21) question. It was given 52 members average age is 32yrs. But it was given in the answer as 51 and 31. Please correct the correctness. For yesterday's question answer is 25yrs. It is like this.
Sum of their ages =52*32=1664
7yrs back their total age=52*32-52*7=1300
Now their average age =1300/52=25yrs. Option 1.
Thanking you.

Dear Admin I can not understand your prize policy. I was the winner of the week 18-22 Jan 2021. But neither you mention it here nor you gave me the prize money. You just skipped that week and went on to declare the next week's result. It is ridiculous. This site was one of the most favourite sites for me but this kind of incident has made me to dislike it now.

For the Puzzle dated 8th December 2020
Answer shown is wrong-
Question:
Vijay can do a certain work in 16 days. Subham is 60% more efficient than Vijay. How many days does Subham alone take to do the same work?
Solution:
Just to help understand lets assume Subham was 50% more efficient:
16days *0.5 = 8 days
So for 60% efficiency
Time taken should be lesser than 8 days
But in the final answer provided it is shown as 10 days!

So where did it go wrong?
60% more efficiency => (100-60)% = 40% time is enough
=> 16*40/100 = 6.4 days
= Option (10)

@admin, please look into this
@Everyone, open to brainstorm on this if need more clarification

Devendra Marghade 3 years ago

Vijay's 1 day work=1/16
Subham's 1 day work=(1/16)*(160/100)=1/10
.'. Subham alone can do the same work in 10 days.

Like? Yes (4) | No

G.S.Kantharao 3 years ago

Varun I think you are mistaken.
Vijay can do the work in 16 days
Then he can do 1/16 th part.
Subham is 60% more efficient. It means if vijay do 1 unit Subham can do 1.6 units
If Vijay do 1/16 work per day Subham can do =(1/16)*1.6=(1/16)(16/10)=1/10
So subham complete the work in 10days.

Like? Yes (2) | No

Varun 3 years ago

Thank you both, very much appreciate the time spent to help understand.
So where I did go wrong is:
Example of 50% more efficiency -
Work Efficiency: Vijay 1, Subham 1.5
Per day work: Vijay 1/16, Subham 1/16*1.5
So 1/16*1.5 = 1.5/16 =>
16/1.5 days = 10.666 days
Similarly for 60% case -> 16/1.6 = 10 days

Thanks again. 😊

Hi Vinoth, it is calculated from the moment the puzzle has been posted. Everyday the puzzle appears at 11AM. So if the answer is submitted at 16:13 total time = 16:13-11 = 4 hours 13 minutes

This type of calculation is necessary because the puzzle can be viewed even without logging in (or by logging in from other (person's) account)
Happy puzzle solving
