A can complete a project in 20 days while B can complete same project in 30 days. If A and B start working together and A leaves the work 10 days before completion of project, then in how many days the project will be completed?

Inline Geek 10 years ago

in one day A completes 1/20th of work, and B completes 1/30th of work. if both works together then work completed in one day will be =
1/20 + 1/30 = 1/12

that means it will take 12 days to complete the work when working together.
but A leave 10 days before actual completion of work that means after A leaves, B has to work 10 more days to complete the work means i.e. 1/3rd of the work.
that means 2/3rd of work is done by both together so number of days:

= no. of days (A & B) + no of days( B alone)
= 12 * (2/3) + 10 = 18 days

Inline Geek 10 years ago

A (13.5 M : 0W) B (0M : 13.5W)
when 4.5 ltr milk poured from A to B:
A (9 M : 0W) B (4.5M : 13.5W)

again 4.5 ltr poured from B to A :

A (9 + 1.125 M : 3.375W) B (3.375M : 10.125W)
in A, milk concentration is 10.125, and in B water is 10.125. so concentration of both are same.

welcome kanika.....first take a practice test from previous papers of tcs, then solve it by yourself in 1hour. then see the solution and check any shortcut methods are there.
from my opinion if you can do more than 22 correctly then you can definitely crack it.
if you practice the papers it is sufficient. you can refer the book of quantitative aptitude by arun sharma (for shortcuts for various chapters .

mohan bylapudi 10 years ago

2299=11*11*99
so u have to write (75-a)(75-b)(75-c)(75-d)(75-e)=11*19*11
(75-64)*(75-56)*(75-86)*(75-76)*(75-74)=11*19*-11*-1*1
therefore a+b+c+d+e=64+56+86+76+74=356

following possibilities are true?

A. All suspects are lying.
B. leftmost suspect is innocent.

a) A only
b) A or C
c) A or B

d) B only

BHASKAR MANDAL 10 years ago

if we consider the first option then we can find out that all are lying means all the persons right to a person are not guilty. => left most is the left person who is guilty. ( i.e, the first person)

if we consider the b option then nothing can be concluded

from the first option it is clear that leftmost is guilty
so the answer will be option (b) A or C

A sheet of paper has statements numbered from 1 to 40. For all values of n from 1 to 40,
statement n says: ‘Exactly n of the statements on this sheet are false.’ Which statements are
true and which are false?

a) The even numbered statements are true and the odd numbered statements are false.
b) The odd numbered statements are true and the even numbered statements are false.
c) All the statements are false.
d) The 39th statement is true and the rest are false

I request anyone to solve this question and explain me the preocedure..

Reply Like? Yes (1) | No

Ram 10 years ago

STATEMENT 0 : Suppose if one of the 1 to 40 statements is true then that means Remaining statements should be false otherwise statement itself is false which is a contradiction.

Example: if 10th statement is true i.e EXACTLY 10 of the statements on this sheet are false means remaining 30 statements are true and each 30 statements says exactly there no. of statements are false that means 10 th statement is false ----contradiction.

so option a,b are eliminated ( since they are having more than 1 statement is true).

if option is c , that means all 40 statements are false => 40th statement is true which is again contradicts the answer.
so finally we can conclude that only one of the statements is true and remaining are false
this is said by statement 39th that Exactly 39 of the statements on this sheet are false
=> 1-38 statements +40 th statement are false .

This Whole question is played by word EXACTLY which decides whether the statement is true or false

OPTION: d is the right answer

You have Rs.2 with u.You have to play a game in which if u win u will get 1 Re. and if lost you will lose 1 Re.You can lose up to 3 times. But if u get 5 Rs, you are left out of the game. In how many ways is this possible?

Reply Like? Yes (2) | No

Ram 10 years ago

Answer is 111 ( if losing is up to 3 times means i can lose either 3 times max or 2 times or 1 time or no losses in a single game )
no. of losses=no. of winnings + extra 3 winnings to get 5 Rs. and leave the game
( i already have 2 Rs. so i need 3 Rs. to leave the game)
1st strategy: LLL WWW WWW ( 3 losses=3 wins so money is balanced and 3 wins= 3rs to get 5rs and leave the game) ------different ways of this case is possible =[9!/(6!*3!)] = 84
2nd strategy: LL WW WWW
----------------------different ways of this case is possible =[7!/(5!*2!)] = 21
3rd strategy: L W WWW
----------------------------different ways of this case is possible =[5!/(4!)] = 5
4th strategy: WWW (No losses)
-------------------------different ways of this case is possible =1
Total No. of Ways = 84+21+5+1
= 111
