The IT giant Tirnop has recently crossed a head count of 150000 and earnings of $7
billion. As one of the forerunners in the technology front, Tirnop continues to lead the way in
products and services in India. At Tirnop, all programmers are equal in every respect. They
receive identical salaries and also write code at the same rate. Suppose 14 such programmers
take 14 minutes to write 14 lines of code in total. How long will in take 5 programmers to
write 5 lines of code in total ?
(a) 19
(b) 5
(c) 14
(d) 70
Read Solution (Total 7)
-
- use the eqn (men*time)/work
(p1*t1)/l1=(p2*t2)/l2
(14*14)/14=(5*t2)/5
14=t2
time taken = 14 - 13 years agoHelpfull: Yes(37) No(1)
- 14 minutes
(14 men)*(14 min)/(14 lines)=(5 men)(x min)/5(lines)
hence x=14 - 13 years agoHelpfull: Yes(8) No(0)
- use Eqn---
MDH/W ie Man*Day*hour/Work
(14*14)/14=(5*D)/5
D=14 :) - 12 years agoHelpfull: Yes(7) No(0)

- In 1min write 1 line code
14 prog 1min 1 line code => 1prog 1min write= 1/14 line
let x min write 5 lines code.
In 1min write 5/x line of code
1 prog 1min = 1/x line of code
1/x = 1/14 => x=14 - 10 years agoHelpfull: Yes(1) No(0)
- in 14 minutes 14 programmers write 14 lines ,that means each programmer writes 1 line in 14 minutes
so 5 programmers will take 14 minutes to write 5 lines as each programmer is writing 1 line only. - 6 years agoHelpfull: Yes(0) No(0)

The Barnes Foundation in Philadelphia has one of the most extra-ordinary and
idiosyncratic collections in French impressionist art. Dr. Barnes who put together this
collection has insisted that the paintings be hung in a particular manner specified by him at a
museum designed by the French architect Paul Philippe Cret who also designed the Rodin
Museum. The museum has, say, seven galleries – Eugene Boudin, Cassatt, Boudin, Forain,
Gonzales, Manet and Monet. Visitors reach the main Eugene Boudin by an elevator, and they
can enter and leave the exhibition only through Eugene Boudin gallery. Once inside, visitors
are free to move as they choose. The following list includes all of the doorways that connect
the seven galleries: There is a doorway between Eugene Boudin and Cassatt, a doorway
between Eugene BoudinandBoudin, and a doorway between Eugene Boudin and Gonzales
galleries. There is a doorway between Cassatt and Boudin galleries. There is a doorway
between Gonzales and Forain and a doorway between Gonzales and Manet galleries. There is
a doorway between Manet and Monet galleries. Which of the following rooms CANNOT be
the third gallery that any visitor enters ?
(a) Monet
(b) Boudin
(c) Forain
(d) Cassatt
