@gupanki2 said:Kunal has only 25 paise and 50 paise coins with him. The total amount in 50 paise denomination is Rs 4 more than the total amount in 25 paise denomination. The no. of 25 paise coins is 20 more than the number of 50 paise coins. What s the total amount with kunal?
31?

Yup, 25 is correct.
Three cases:-
i) No diagonal movement, three east steps and 2 north
i) No diagonal movement, three east steps and 2 north
C(5, 2) = 10 ways
ii) One diagonal movement, so 1 NE step, 2 east step and 1 north step
4!/(1!1!2!) = 12 ways
iii) Two diagonal movements, so 2 NE steps, 1 east step
3!/(1!2!) = 3 ways
Total = 25

it is an IIFT question and one digit '4' is missing in it.

i mentioned 4..is it twice?
A simple one :A couple has two children. The probability that the first child is a girl, is 50%. The probability that the second child is a girl, is also 50%. They tell you that they have a daughter. What is the probability that their other child is also a girl ?

Possible cases
DD -> prob. = 1/2
SD -> prob. = 1/2
DS -> prob. = 1/2
Required probability = (1/2)/(3/2) = 1/3
@Brooklyn
DD -> prob. = 1/2
SD -> prob. = 1/2
DS -> prob. = 1/2
Required probability = (1/2)/(3/2) = 1/3

DD=>1/2*1/2 =1/4 ? same for others ...isn't?
Though ans wont change

No.. one of their children is a daughter.. this is given.. so that probability is not included...
