The sum of Tina and Tuffy age is equals thrice their Mather's age. Tina is 2 years younger than Tuffy. If the age of mother is 42, find the difference between age of mother and elder child.

Taffy=x elder child

Tina =x-2 younger child

Given condition:

3(Tuffy+Tina)=Mother

3(x-2+x)=42

6x-6=42

6x=48

x=8

Tina =6

Tuffy=8

In a family, there are six members A, B, C, D, E and F. A and B are a married couple, A being the male member. D is the only son of C, who is the brother of A. E is the sister of D. B is the daughter-in-law of F, whose husband has died. How is F related to C?

Option (C) A is a male and married to B. So, A is the husband and B is the wife. C is the brother of A. D is the son of C. E, who is the sister of D will be the daughter of C. B is the daughter-in-law of F whose husband has died means F is the mother of A. F is the mother of A and C is the brother of A. So, F is the mother of C.

A + B means A is the son of B;

A - B means A is the wife of B;

A x B means A is the brother of B;

A Ã· B means A is the mother of B; and

A = B means A is the sister of B.

What does P = R Ã· Q mean?

Option (A)

P = R Ã· Q means P is the sister of R who is the mother of Q i.e. P is the aunt of Q.

So, the answer is (a).

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

Find out the incorrect number

11, 2, 21, 3, 32, 4, 41, 5, 51, 6

Find out the incorrect number

11, 2, 21, 3, 32, 4, 41, 5, 51, 6

The given sequence is a combination of two series:

I. 11, 21, 32, 41, 51 and

II. 2, 3, 4, 5, 6.

Clearly, the pattern in I is + 10.

So, 32 is wrong and should be replaced by (21 + 10) i.e. 31.

Choose the term which will continue the following series : P 3 C, R 5 F, T 8 I, V 12 L, ?

Clearly, the first letters of the terms are alternate.

The sequence followed by the numbers is + 2, + 3, + 4, ... .

The last letter of each term is three steps ahead of the last letter of the preceding term.

Thus, the next term would be X 17 O.

Hence, the answer is (c).
