John has 30 Marbles ,18 of which are red and 12 of which are blue. Jane has 20 Marbles all of them either red or blue. If the ratio of the red Marbles to the blue Marbles is the same for both John and jane, then John has how many more blue marbles than Jane?

John marble ratio:

read :blue

18 :12

3: 2

Jane Marbles are also with the same ratio as john.

Red: blue. total

3: 2. 20

3 X + 2 x = 20 = > 5 x = 20= >X = 4

2 X = 2( 4 )= 8 blue marbles

John have: 12 - 8 = 4 blue Marbles than jane

A person speed at a rate of 40 km per hour. If he increases his speed by 20% what is his new speed in metre per minute?

Original speed= 40 km per hour

If the speed is increased by 20%

Then the new speed 20% of 40=8 km per hour

That is distance covered in 1 hour =8 km

Distance covered in 60 minute= 8000 m

The artist distance covered in 1 hour =8 km

Distance covered in one minute =133.3 m

.
On dividing 2272 as well as 875 by 3-digit number N, we get the same remainder. The sum of the digits of N is:

Clearly, (2272 - 875) = 1397, is exactly divisible by N.

Now, 1397 = 11 x 127

The required 3-digit number is 127, the sum of whose digits is 10.

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

a _ cacbc _ baca _ _ b

The series is abcac / bcaba / cabcb. Thus, the series consits of three sequence. The first three letters of each sequence are in a cyclic order and the last two letters of each sequence are the same as the first and third letters of the sequence.

A Boat covers a distance of 30 km downstream in 2 hours while it takes 6 hours to cover the same distance upstream. What is the speed of the boat in kilometre per hour?

Let B and S be the speed of boat and stream respectively

As per the given conditions

30/(B+S)=2

30/(B-B)=6

From eq (i) and (ii):

S=5 ,b= 10 km/hr
