122. A can do a piece of work in 14 days which B can do in 21 days. They begin together but 3 days before the completion of the work, A leaves off. The total number of days to complete the work is:
Answer: 10 1/5
Explanation:A's 1 day work = \(\frac{1}{14}\)
B' 1 day work = \(\frac{1}{21}\)
A left 3 day before the completion of work.
B's 3 days' work = \(\frac{1}{21} \times 3 = \frac{1}{7}\)
Remaining work = \(1 \times \frac{1}{7} = \frac{6}{7}\)
(A + B)'s 1 day's work = \(\left(\frac{1}{14} + \frac{1}{21}\right) = \frac{5}{42}\)
Now, \(\frac{5}{42}\) work is done by A and B = 1 day.
or
whole work done by A&B = \(\frac{42}{5}\)
\(\frac{6}{7}\) part of work done by A and B = \(\frac{42}{5} \times \frac{6}{7} = \frac{36}{5}\) days.
Hence, total time taken = (3+36/5)days = \(10\frac{1}{5}\) days.

123. A can do a work in 10 days and B can do the same work in 15 days. So how many days they will take to finish the same work ?
Answer: 6 days
Explanation:First find the 1 day work of both (A & B)
A 1 day's work = 1/10
and
B 1 day's work = 1/15
So (A + B) 1 day's work = (1/10+1/15)
= (3/30+2/30) = 5/30 = 1/6
So Both (A & B) together can finish work in 6 days

124. In a bid two firms A and B competing against each other.If the probability of bid amount quoted by B being lower than that of A is 0.8 and if it is known that the bid is won by the ones who quotes the lowest price,what is the probability that A wins the bid?
Answer: 0.2
Explanation:Probability of 'a' biding lower than 'b' = 1 - 0.8 = 0.2
so probability of wining of 'a' = 0.2
