What is the unit digit in(795 - 358)?

Unit digit in 795 = Unit digit in [(74)23 x 73]

= Unit digit in [(Unit digit in(2401))23 x (343)]

= Unit digit in (123 x 343)

= Unit digit in (343)

= 3

Unit digit in 358 = Unit digit in [(34)14 x 32]

= Unit digit in [Unit digit in (81)14 x 32]

= Unit digit in [(1)14 x 32]

= Unit digit in (1 x 9)

= Unit digit in (9)

= 9

Unit digit in (795 - 358) = Unit digit in (343 - 9) = Unit digit in (334) = 4.

So, Option B is the answer.

If a boat travels with speed 10 kilometre per hour in still water and speed of stream is 5 kilometre per hour what would be the time taken by boat to go 60 km downstream?

Thus, downstream speed=(x+y)km/he=10+5=15 km/hr

We have,

Time=distance/speed

Time taken by a boat to travel 60 km downstream will be equal to the ratio of distancees travel to downstream speed.

Time taken by a boat= 60/15=4 hr

.
A group of workers can do a piece of work in 24 days however as 6 of them were absent it took 30 days to complete the work how many people actually worked on the job to complete it?

Let X workers are required to complete the job.

As workers and days are inversely proportional to each other so

(X-6)/x=24/30

30x-180=24x

6x=180

X=30

Tina can do a piece of work in 20 days. Alfard is 25% more efficient than Tina. Time taken by Alfard to complete the task is?

Ratio of work of Tina and Alfard is=125/100=5/4

Let time taken by Alfard is x

5/4=20/x

x=5/4*20

x=16 days.

10 evacuator works 10 hour daily to remove 2500 cubic feet of Earth in 3 days. How many evacuator work 6 hour daily to remove 5000 cubic feet of Earth in 2 days?

Let x evacuator are required.

Evacuators are inversely proportional to hours and days are directly proportional to work progress

So,

X/10=(10/6)*(5000/2500)*(3/2)

=48
