Explanation

1 hour's work of A = 2.5% (meaning A completes 2.5% of the work in 1 hour)

1 hour's work of B = 1.66% (meaning B completes 1.66% of the work in 1 hour)

Combined work rate of A and B in 1 hour = 2.5% + 1.66% = 4.16%

Time to complete the work = 100%/4.16% = 24 hours (since they work 8 hours a day, this is equivalent to 3 days)

So, A and B together can complete the work in 3 days, working 8 hours a day.

A stock may be bought or sold only if it is listed on an exchange.

Explanation

The average of 50 numbers is 30, so the sum of all 50 numbers is 50 x 30 = 1500.

If we discard 35 and 40, we subtract these from the total sum: 1500 - 35 - 40 = 1425.

Now, we have 48 numbers left (50 - 2 = 48).

To find the new average, we divide the remaining sum by the number of remaining numbers: 1425 ÷ 48 ≈ 29.68.

So, the correct answer is: 29.68

However, note that "He" typically pairs with "has," but this phrasing assumes casual usage.

Explanation

10 persons can do the job in 20 days, which means the total work required is 10 x 20 = 200 person-days.

If 20 persons are working with twice the efficiency, their effective work capacity is doubled, so they can do the work of 40 persons (20 x 2).

Now, let's calculate the time taken by 20 persons with twice the efficiency to complete the same job:

Total work required = 200 person-days

Effective work capacity = 40 persons

Time taken = Total work required / Effective work capacity

= 200 person-days / 40 persons

= 5 days
