A..try to find answer.. if still not able to.. i will provide wd the answer.
Still not able to..from A we can only determine that the possible values of p and q can be..
3,2...4,3 and 5,4
Consecutive positive integers and less than 6..what am i missing here????
1222

some LR pls..

Answer the questions on the basis of the information given below.

There are few persons in a family. A is the mother of D who has only one brother. B is the father of F who is his only married child. The number of siblings of F is the same as the number of his sons. B is the grandfather of D who is female. L is the uncle of M and they both are male. J is a female and is married.These are the only members of this family.

What is the total number of members in the family and how many of them are male?

How is F related to M?

Who is J married to?

u missed "consecutive roots"

wd p=4 and q=3, eqn becomes

x^2-4*x + 3
roots are x=1,3 (not consecutive roots)

wd p=5,q=4. eqn becomes
x^2-5*x + 4
roots x=1,4 (not consecutive roots)

but wd p=3, q=2
roots = 1,2 (consecutive roots)

hence only value satisfying is p=3, q=2

Oh yes..thanks..silly mistake

total = 7
male = 4
F is the father of M
J is married to M (can be B too, its ambiguous)

@krum said:
total = 7male = 4F is the father of MJ is married to M
J is married to B

but " B is the father of F who is his only married child", ??

is it ctct ? if F is his only child, then siblings of F =0, but B has two sons as per soln.. they are L and F..

L is unmarried, but how can u say that J is married to B, she can be married to M too, which statement confirms this?

i interpreted badly.. got u.., and regarding J, is whose wife, m not clr. but soln says B's

Can you please explain how L can be the son of B? Acc to given problem he has only one child which has to be F

Also if the statement F has no siblings holds true, then it must mean that F has no sons as well..right?

its given "only married child", L is his unmarried child

L is F's only sibling and M is his only son, question explicitly say sons and not child
