Bicycle travel first How distance between two place with the speed of 5 kilometre per hour and rest of her sister is the speed of 20 km per hour. The average speed of bicycle is:

Let the total distance covered be" s "km

Total time taken,

=(s/2)/5+(s/2)/20

=5s/40

Average speed,

=s/(5s/40)

=s*(40/5s)

=8 km/hr

The average temperature on Wednesday, Thursday and Friday was 25. The average temperature on Thursday, Friday and Saturday was 24. If the temperature on Wednesday was 30, what was the temperature on Wednesday?

Total temperature on Wednesday, Thursday and Friday was 25 Ã—3 = 75

Total temperature on Thursday, Friday and Saturday was 24 Ã—3 = 72

So, difference b/w the temperature on Wednesday and Saturday = 3

If Wednesday temperatures = 30 ,then Saturday temperature = 30 - 2 = 27

If x and y are the two digits of the number 653xy such that this number is divisible by 80, then x + y = ?

80 = 2 x 5 x 8

Since 653xy is divisible by 2 and 5 both, so y = 0.

Now, 653x is divisible by 8, so 13x should be divisible by 8.

This happens when x = 6.

x + y = (6 + 0) = 6.

In alphabet series, some alphabets are missing which are given in that order as one of the alternatives below it. Choose the correct alternative.

aab _ ab _ cabcca _ bcab _ c

The series is aa / bcab / bcab / ccaa / bcab / bc.

Thus, the pattern ccaa followed by bcab repeated twice, makes up the series.

The speed of swimmer along the flow of river is 40 kilometre per hour and against the flow of river is 22 kilometre per hour what would be the speed of swimmer in still water?

Speed of swimmer (x)=(1)x[downstream speed+upstream speed]/2

X=(40+22)/2=31
