The average of 6 quantities is 4. The average of 3 them is 3. What is the average of the remaining three numbers?

The average of 6 quantities is 4.

Therefore ,the sum of the 6 quantities is 6 Ã— 4 = 24.

The average of three of these 3 quantities is 3.

Therefore, the sum of these three quantities = 3 Ã— 3 = 9

The sum of the remaining three quantities = 24 - 9 = 15 .

Average of these three quantities = 15 / 3 = 5.

In following questions, one term in number series is incorrect.

Find out the incorrect number 3, 4, 10, 32, 136, 685, 4116

Find out the incorrect number 3, 4, 10, 32, 136, 685, 4116

The sequence is as follows:

2nd term = (1st term + 1) * 1

3rd term = (2nd term + 1) * 2

4th term = (3rd term + 1) * 3 and so on.

So, 32 is wrong and must be replaced by (10 + 1) * 3 i.e. 33..

In following questions, a sequence of groups of alphabets and numbers is provided with one term missing , Choose the missing term from options. AB, BA, ABC, CBA, ABCD, ?

The first group of letters is reversed to obtain the second group. The second group is reversed and the next consecutive letter is added to it to obtain the subsequent group..

A test has 20 questions. If Anna gets 90% correct, how many questions did Anna missed?

The number of correct answers is 90% of 20 or 90/100 x 20

90/100 x 20 = 18

Since the test has 20 questions and she got 18 correct answers, the number of questions she missed is 20-18=2

Anna missed 2 question.

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 _ c _ abb _ a _ bc _ bc _ ab

The series is abccab / bcaabc / abccab.

Obviously, the pattern abccab / bcaabc is repeated.

.
Look at this series: 21, 9, 21, 11, 21, 13, . . .

What number should come next?

What number should come next?

In this alternating repetition series, the random number 21 is interpolated every other number into an otherwise simple addition series that increases by 2, beginning with the number 9.

In this Series 21 is common random number.

Now add 2 with 9.

9 + 2 = 11

21 is next common number.

11 + 2 = 13

21 is next common number.

13 + 2 = 15.

21 is next common number.

So the answer is 21..

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

_ bcdbc _ dcabd _ bcdbc _ dc _ bd

The series is abcd / bcad / cabd / abcd / bcad / cabd. Thus, the pattern abcd / bcad / cabd is repeated twice.
