In following question,a number series is given with one term missing. Choose the correct alternative

4 , 9 , 5 , 12 , 7 , 15 , 8 , x , 10.

4 , 9 , 5 , 12 , 7 , 15 , 8 , x , 10.

The given sequence is a combination of two series :

4 , 5 , 7 , 8 , 10 and 9 , 12 , 15 , (...).

the missing term is 18..

Jimmy bought 60 Mangoes and 40 Apples. He found 30% of Mangoes and 10% of apples were overripe. Find the number of fruit in good condition.

Total fruit = 60 + 40 = 100

Overripe Mangoes = 30% of 60

= 30/100 x 60

=18

Overripe Apples = 10% of 40

= 10/100 x 40

=4

Total number of overripe fruit= 18+4=22

Therefore Number of fruit in good condition= 100-22= 78

The average weight of a class of 9 student is 40 kg. If the weight of the teacher be included, the average rises by 1 kg. The weight of the teacher is :

Weight of the teacher

=total weight with teacher - total student weight

= (10 x 41 - 9 x 40) kg

= (410 - 360)kg

= 50 kg is weight of teacher

E is
the son of A.

D is the son of B.

E is married to C.

C is B's daughter.

How is D related to E?

Jane and Naura are age fellows. The total age of Miley and Naura is 7 years more than the total age of Jane and Bell

Bell is how many years younger than Miley.

Let's

Naura and jane have same age = X

Miley + x = 7 + x + Bell

=> Miley - Bell = 7 + X - x = 7

=> Bell is younger than Miely by 7 years

Two bus tickets from city A to B and three tickets from city A to C cost Rs. 77 but three tickets from city A to B and two tickets from city A to C cost Rs. 73. What are the fares for cities B and C from A ?

Let Rs. x be the fare of city B from city A and Rs. y be the fare of city C from city A.

Then, 2x + 3y = 77 ...(i) and

3x + 2y = 73 ...(ii)

Multiplying (i) by 3 and (ii) by 2 and subtracting, we get: 5y = 85 or y = 17.

Putting y = 17 in (i), we get: x = 13.

In following number series, either one term is missing or is incorrect.

Choose correct answer from options 1, 5, 11, 19, 29, 55

Choose correct answer from options 1, 5, 11, 19, 29, 55

The correct sequence is + 4, + 6, + 8, + 10, ....

So, next term after 29 = 29 + 12 = 41.

The term after 41 will then be (41 + 14) i.e. 55.

41 is missing..

In three coloured boxes - Red, Green and Blue, 108 balls are placed. There are twice as many balls in the green and red boxes combined as there are in the blue box and twice as many in the blue box as there are in the red box. How many balls are there in the green box ?

Let R, G and B represent the number of balls in red, green and blue boxes respectively.

Then,

R + G + B = 108 ...(i),

G + R = 2B ...(ii)

B = 2R ...(iii)

From (ii) and (iii), we have G + R = 2x 2R = 4R or G = 3R.

Putting G = 3R and B = 2R in (i), we get:

R + 3R + 2R = 108; 6R = 108 ;R = 18.

Therefore Number of balls in green box = G = 3R = (3 x 18) = 54.

.
K is the brother of N and X,Y is the mother of N and Z is the father of K. Which of the following statement is not definitely true.

K is the brother of N and X . so ,Y who is the mother of N and Z , who is the father of K ,will be mother and father of all three. however ,it is not mentioned whether N is male or female..

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

Find out the incorrect number

3, 7, 15, 39, 63, 127, 255, 511

Find out the incorrect number

3, 7, 15, 39, 63, 127, 255, 511

Each number in the series is multiplied by 2 and the result increased by 1 to obtain the next number.

So, 39 is wrong and should be replaced bu (15 * 2 + 1) i.e. 31..

What will be the next term?

BDF, CFI, DHL, ?

BDF, CFI, DHL, ?

Clearly, the first, second and third letters of each term are respectively moved one, two and three steps forward to obtain the corresponding letters of the next term.

So, the missing term in EJO.

Hence, the answer is (C)..

Complete the Given Series

Which number replace question mark in the series 7, 12, 19, ?, 39.

Which number replace question mark in the series 7, 12, 19, ?, 39.

Clearly, the given sequence follows the pattern:

+5, +7, +9 ... i.e., 7 + 5 = 12, 12 + 7 = 19, ... .

So Missing Number = 19 + 9 = 28.

Hence, the answer is (B)..
