Maths Quotes

mathematics is the art of managing numbers with mindful manner.

rekha gupta

Pure mathematics is the world's best game. It is more absorbing than chess, more of a gamble than poker, and lasts longer than Monopoly. It's free. It can be played anywhere - Archimedes did it in a bathtub.

8 men and 10 women are working together on a job and can complete it in 10 days. The work done by each woman is four-fifth of the work by each man. In how many days 10 men alone can complete the same work?

Reply Like? Yes | No

(5 years ago)

Ans: 16 Days

Total Work = (8m + 10w)*10
Given, w=(4/5)m
So, total work in terms of m = [8m + 10*(4/5)m]*10 = 160m
Hence time taken for 10 men=160m / 10m = 16 Days.

Rohit brushed quickly past an elderly woman waiting on the platform ahead of him to get onto the metro. He wanted to be sure to get a seat to read his Economic Times. As the train rolled out of the station, he lifted his head from the newspaper
and stared at the man directly across from him.
A tsunami - of antipathy came over him. Rohit knew this man, knew him all too well.
Their eyes locked.
As the train reached full speed, the ruckus of speeding wheels against the winding
rails and a wildly gyrating subway car filled Rohit's ears. To this frenetic beat, Rohit
effortlessly listed in his head all the reasons this man, whose eyes he stared coldly
into, was an anathema to him.
He had climbed the upper echelons of his firm using an imperious manner with his
subordinates, always making sure everyone knew he was the boss.
Despite his impoverished upbringing, he had become ostentatious. Flush with cash
from the lucrative deals he had made, he had purchased a yacht and a home in
Mumbai. He used neither. But, oh, how he liked to say he had them. Meanwhile,
Rohit knew, this man's parents were on the verge of being evicted from their rundown
tenement apartment in Allahabad.
What bothered Rohit most about this man was that he never even attempted to make amends for his evil ways.
Could this man change? Rohit did not know. He could try though.
The train screeched to Rohit's stop. He gave the man one last hard look. "See you
around," he mumbled to himself. And he knew he would, because Rohit had been
glaring at his own reflection in the glass in the metro.
It would take years of hard work and therapy, but Rohit would one day notice this
man again on the train and marvel at what a kinder person he had become.
I) Why did a tsunami of antipathy come over Rohit?
a) Because he was angry at himself and unable to stand looking at himself
b) Because the man sitting across him was his former boss who treated him badly
c) Because he wanted to read his newspaper and not be disturbed, especially by someone he disliked d) Because the guy sitting across him was financially better off than Rohit

II)What does it mean to have an imperious manner with underlings?
opt.
1.To ignore them

2.To be stoic around them

3.To openly humiliate them

4.To not be affected by them

5.To be domineering towards them
III)Which statement makes most sense from what is said in the paragraph?
a) Rohit has few friends b) Rohit knows himself well
c) Rohit has had a difficult life d) Rohit is incapable of change

IV) What was the biggest reason (stated or implied) for Rohit disliking the man in the metro?
a) The man was known to be extremely rude and domineering especially with his subordinates
b) The man was remorseless and had not made any effort to reform himself for the better
c) The man did not bother to take care of his parents who were on the verge of being evicted from their humble dwelling
d) The man did not have respect for things or money and while people did not have a place to stay, he had bought a flat which he did not even use
Iv) What does it mean to have an imperious manner with underlings?
a)To ignore them b)To be stoic around them
c)To openly humiliate them d)To not be affected by them
e)To be domineering towards them

2, 35, 104, 209, ? .. what will be next after 209. Please explain with logic

Reply Like? Yes | No

(5 years ago)

2, 35, 104, 209

Difference between 2nd and 1st, = 35 - 2 = 33

Between 3rd and 2nd = 104 - 35 = 69

Between 4th and 3rd = 209 - 104 = 105

Now, difference between the values obtained -

69 - 33 = 36

105 - 69 = 36

It is clearly seen that the difference is increasing by 36.

So, the next number in the series will be = (105 + 36) + 209

= 141 + 209

= 350

Hence, the next number in the series is 350

= 2^(4*41) +2^7925 +2^(4*n)
= 2^(164) + 2^7925 + 2^(4*n)
compare it with a^2 +2ab+b^2
= (2^82)^2 + 2*2^82 * 2^2*n + (2^2*n)^2
so, 2*2^82 * 2^2*n =2^7925
or, 2^82 * 2^2*n =2^7924
or, 2^(82+2n) =2^7924
or, 82+2n =7924
