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..

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..

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

.
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)..

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.

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..

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
