In following alphabet series , one term missing as shown by question mark . Choose missing term from options.

Z, S, W, O, T, K, Q, G, ?

The given sequence consists of two series :

I. Z, W, T, V, Q, ? in which each letter is moved three steps backward to obtain the next term.

II. S, O, K, G in which each letter is moved four steps backward to obtain the next term.

In following number series, two terms have been put within brackets. Choose the appropriate option

Choose the appropriate option 3, 10, 29, (66), (127), 218

Choose the appropriate option 3, 10, 29, (66), (127), 218

The sequence is 1

Clearly, both the terms 66 and 127 are correct..

Salesman, engineer and accountant. There are two married couples in the family. D, the salesman is married to the lady teacher. The doctor is married to the lawyer. F, the accountant is the son of B and brother of E. C, the lawyer is the daughter in law of A . E is the unmarried engineer. A is the grandmother of F. Which of the following is one of the couples?

C is the daughter in law of A who is the grandmother of F means C is the mother of F. But F is the son of B. So, B is c's husband. But C, the lawyer, is married to the doctor. So, B is the doctor. F, the accountant, will be the son of B and C. E is the unmarried engineer. So, the unmarried couples can be that of grandmother of F i.e. A and D .But D, the salesman is married to the lady teacher. So, D, the salesman, is the grandfather of F, father of B and the husband of A, the lady teacher.

The two couples are C and B; and D and A which is none among the choices.

What numbers should come next?

What numbers should come next?

In this simple subtraction series, each number is 6 less than the previous number.

Rule = (1st number), (1st no. - 6 = 2nd no.), (2nd no. - 6 = 3rd no.). . .

Now in our case,

(84), (84 - 6 = 78), (78 - 6 = 72), (72 - 6 = 66), (66 - 6 = 60), (60 - 6 = 54), (54 - 6 = 48), (48 - 6 = 42), (42 - 6 = 36).

So the answer is B = 42, 36.

In following questions, a sequence of groups of alphabets and numbers is provided with one term missing , Choose the missing term from options. LXF, MTJ, NPN, OLR, ?

The first letter of each term is moved one step forward, the second letter is moved four steps backward and the third letter is moved four steps forward to obtain the corresponding letters of the next term.

The sum of how many terms of the series 6 + 12 + 18 + 24 + ... is 1800 ?

This is an A.P. in which a = 6, d = 6 and Sn = 1800

Then, n/2[2a + (n - 1)d] = 1800

n/2[2 x 6 + (n - 1) x 6] = 1800

3n (n + 1) = 1800

n(n + 1) = 600

n2 + n - 600 = 0

n2 + 25n - 24n - 600 = 0

n(n + 25) - 24(n + 25) = 0

(n + 25)(n - 24) = 0

n = 24

Number of terms = 24.

In following number series, two terms have been put within brackets. Choose the appropriate option

Choose the appropriate option (2), 5, (12), 25, 41, 61

Choose the appropriate option (2), 5, (12), 25, 41, 61

The correct sequence is + 4, + 8, + 12, + 16, + 20.

Clearly, 2 is wrong and must be replaced by (5 - 1) i.e. 4.

Also, 12 is wrong and should be replaced by (5 + 8) i.e. 13..

A person travel at the rate of 60 miles per hour and cover 300 miles in 5 hours. If he reducing is paid by 10 miles per hour how long will it take to cover the same distance?

Original speed= 60 miles per hour

If the speed is reduced by 10 miles per hour.

Then the new speed= 50 miles per hour

Distance to be covered= 300 miles

Time= distance/speed

Time=300/50

Time=6 hr

A special cereal mixture contains rice, wheat and corn in the ratio of 2:3:5. If a bag of the mixture contains 3 pounds of rice,how much corn does it contains?

Ratio of cereal:

Rice, wheat, corn

2 :3 :5

If price are 3 pounds then corn:

3/2=1.5

Ratio of corn = 5 x 1.5 = 7.5

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

The series is aababcabcddcbacbabaa. Thus, the letters equidistant from the beginning and the end of series are the same.
