it takes 8 , 12 and 16 days for A , B and C to complete to
task . how many days will it take if A works on the job for
2 days and then B works on it until 25 % of the job is left
for C to do , and C completes the work ?
Answer Posted / sabarish
12 days.
work done by A in 1 day = 1/8.
for 2 days its 1/4.
remaining work is 1-1/4=3/4.
25 % of work is done atlast be C.
thrfore it is 1/4.
work done by B = 3/4-1/4 = 1/2.
days for B to complete is (1/2) /(1/12) = 6
days for C to complete 1/4 of the job (1/4) /(1/16) = 4.
A takes 2 days , B takes 6 days and C takes 4 days.
total is 12 days.

Alok and Bhanu play the following min-max game. Given the expression N = X - Y – Z where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be • 4 • -18 • 9 • 2
