I need help in solving this sequence:

24, 333333, ?, ?, 53, 44444444, 82, ?, ?, 222244444444, ?, ?, ?, 444433333322221

reposting this because I wanted to add more informations. Now by taking a look at the numbers that preceed 333333 and 44444444,we can see that 2+4=6 and after that we can see that 333333 is made of 6 numbers, the same goes for 5+3=8 we have 8 numbers 4 there.

Now take a look at 53, 44444444, 82 you can see that the number that preeceds 44444444 is 82-30+1=53 so i just assumed that for the next number we should use 82+30-1=111 11+1=12 222244444444 has 12 numbers and the criteria starts working now we do the same 111+30-1=140 and we put it right after 222244444444 ,then we do again 140+30-1 we firstly do 140+30=170 now we subtract -1 from 0 and for some reasons it becomes 16-1 now 16-1=15 and 444433333322221 has 15 numbers so by substituting these values from the original sequence we get this one:

24, 333333, K, ?, 53, 44444444, 82, ?, 111, 222244444444, 140, ?, 16-1, 444433333322221

I'm unsure about k,because by using my criteria that should have been 24+30-1=53 but we find that later before 44444444. The only thing i know is that after 82 we need a 10 digit number,because of 8+2=10, after 140 we need a 14 digits number please help me

Reply Like? Yes | No

(13 Days ago)

Answer is 3
If you pick 2 socks then chances are that both are of two different colors.
When you pick 3 for sure two would be of the same color (as the socks are only of two colors Red and White)

person earns Rs. 2000 per month over and above his salary as additional charge allowance. However, 30% of this additional income will be deducted as additional income tax at source. If the person would deposit Rs. 1000 per month on a long term saving fetching 12% interest his tax liability on the additional allowance would reduce to 10%. What is the effective interest for this person for money invested in the long term savings scheme?

Reply Like? Yes | No

(19 Days ago)

If he will not invest Rs 1000, per month, balance amount left with him after tax= Rs 1400/-
After investing Rs 1000/- per month, balance amount after tax and investment = Rs. 800/-
So effectively, he paid Rs. 600 for investment of Rs 1000 for which he is getting annual interest of Rs. 120.
so effective rate of interest = 120*100/600= 20%

Three friends divided some bullets equally. After each of them shot 4 bullets, total number of bullets remaining is equal to the bullets each had after division. Find the original number of bullets:

(b) 17
(c) 20
(d) 18

Reply Like? Yes (1) | No

(24 Days ago)

18

Each had 6 bullets after division.
After each of them shot 4 bullets, each one had 2 bullets now and hence total number of bullets remaining (2x3=6) is equal to the bullets each had after division (6).

to solve it
if x is number of bullets with each person after division, then
3*(x-4)=x
x=6

Social scientists have found that people who marry young are seldom prepared for marital roles. Also the men and women who marry as young adults live longer than those who never marry. According to a study, young adults who are about to get married have fewer unhealthy habits, like smoking and uncontrolled drinking of alcohol, as compared with the other people of the same age.

1)The institution of marriage forces young men and women to quit smoking and drinking
2)Those who marry at an older age live a shorter life than those who get married at a younger age.
3)People who marry at an older age are well prepared to take up marital roles
4) Young adults who are not about to marry are more likely to have unhealthy habits than those who are about to marry.

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

(1 Month 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
