X and Y can do a piece of work in 20 days and 12 days respectively. X started the work alone and then after 4 days Y joined him till the completion of the work. How long did the work last?

prativasahoo 6 years ago

workdone by x in 4 days=4*(1/20)=1/5
remaining work=1-1/5=4/5
work done by both x & y in 1 day =(1/20)+(1/12)=2/15
2/15 work is done by x&y in 1 day
then 4/5 work is done by x&y =(4/5)*(15/2)=6 days
total time taken to complete the work is 6+4=10 days

How do you came up with snow white and seven dwarfs problems answer
The Seven Dwarfs are having breakfast, and Snow White has just poured them some milk. Before drinking, the dwarfs have a ritual. First, Dwarf #1 splits his milk equally among his brothers' mugs (leaving himself with nothing). Then Dwarf #2 does the same with his milk, etc. The process continues around the table, until Dwarf #7 has distributed his milk in this way. (Note that Dwarf #7 is named Dopey!) At the end, each dwarf has exactly the same amount of milk as he started with! If the total amount of milk was 42 ounces.

Q1. how many have empty mugs?
Q2. how many have amount of milk in mug as a prime no.

Reply Like? Yes (1) | No

Manav 7 years ago

1. Only one mug ( of Dwarf #7) was empty.
2. only one mug ( dwarf#6) had 2 ounces which is prime number.

Distribution of milk was 12, 10,8,6,4,2,0.

A robot is designed to move in a peculiar way and it can be set in motion by a microprocessor program. The program can be initiated by assigning a positive rational value to its variable n. The program directs the robot to move in the following way. As soon as the program is started, the robot starts from the point O, moves 2n metres northward and changes its direction by n° to the right. It then moves 2n metres forward and again changes its direction by n° to the right and continues in this manner till it reaches the starting point O, or till it covers a total distance of 100 m, whichever happens first, and then it stop.
Q: 8. I assigned a value for n and started the program. If the robot finally came back to O and stopped, what is the total distance that it has covered
(1) 180 m
(2) 360 m
(3) 720 m
(4) Cannot be determined

Q: 9 For how many value of n in the intervals [1, 60] does the robot cover less than 1000 m, before it stops?
(1) 19
(2) 60
(3) 355
(4) Infinite

The simplest way to find the sum of consecutive no.s
For ex. 1+2+3+4+5+6+7+8
Therefore,we should first find the sum of first and last digit.
1+8=9
Then we should multiply it by the half of no.s
That is,
8/2
( because there are 8 no.s)
The sum is
(8+1)×(8/2)
9×4=36
