Rajiv can do a piece of work in 10 days , Venky in 12 days and Ravi in 15 days. They all start the work together, but Rajiv leaves after 2 days and Venky leaves 3 days before the work is completed. In how many days is the work completed ?

Reply Like? Yes | No

(10 years ago)

this question actually says that all will start the work together
if they will wok together work get completed in 4 days as LCM OF(10,12,15)/((LCM OF(10,12,15)/10)+(LCM OF(10,12,15)/12)+(LCM OF(10,12,15)/15)) this will give the no. of days needed to complete the task.
but rajiv will leave after 2 days
so the other 2 days work will be done by venky and ravi which will be (1/2)of work
but venky will also leave before 3 days of work completion
so for last three days ravi will work alone
now calculate work done by ravi in 3 days
if in 15 days 1 work is completed
in 1 day 1/15 work is completed
and in 3 days 1/5 work is completed
as 1/2 work is lef and 1/5 will be done by ravi
so 1/2-1/5 = 3/10 of work will be done by both venky and ravi
1 work is completed in 10 days by both as(LCM(12,15)/SUM OF RATIO i.e (4+5) will give the no. of days of work completion)
3/10 of work will be completed in 3/10*10=3 days
so the work will be completed in 8 days.

The cycle consists of the following steps which may or may not be the proper sequence of the execution.
1. Fetch the operand from the memory
2. Execution
3. Fetch instruction
4. Decode the instruction
5. Result
In which of the following steps, is the Program Counter(PC) loaded with the address of the next instruction?

18. Let f(m,n) =45*m + 36*n, where m and n are integers (positive or negative) What is the
minimum positive value for f(m,n) for all values of m,n (this may be achieved for various
values of m and n)?
a. 9
b. 6
c. 5
d. 18

Reply Like? Yes (1) | No

(10 years ago)

ANSWER:9
EXPLANATION:Trail and error
if we assume the least values for m,n are 1,-1.Then f(m,n)=(45*1)+(36*-1)=9
if we assume the least values for m,n are 2,-2.Then f(m,n)=(45*2)+(36*-2)=18.
therefore 9 is the least value of f(m,n)....

Reply Like? Yes | No

(10 years ago)

both are similar,
speed * time = distance ( here speed can be called as distance rate )
and
work rate * time = work

so in work problem try to make the work rate in percentage then it will be easy
e.g, if a can do work in 5 days
so the work rate in percentage will be 100/5 = 20% , use it as 20 in the above equation
and then the work on the right side will be 100
