Answers
Answer:
The Total number of children does Kunal have is 7 children .
Step-by-step explanation:
Given as :
Three statement are as follows
(I) The children of Kunal are Dhaval and Deepa
(II) Dhaval has twice as many sisters as he has brother
(III) Deepa has the same no of sisters as she has brother
Let The Total number of children does Kunal have = n children
According to statement
∵ Dhaval has twice as many sisters as he has brother
So, except Dhaval and Deepa there are other sibling also
i.e If except Deepa , there are three more girls then total number of sisters does Dhaval have become four .( Deepa + 3 more ) ........1
And Since Dhaval has twice as many sisters as he has brother
So, Dhaval must have two brother excpet him
Again
∵ Deepa has the same no of sisters as she has brother
So, Deepa have three sister from statement 1
And Deepa must have three brothers also , (Dhaval + 2 more)
So, Total number of children does Kunal have = Deepa + 3 more + Dhaval + 2 more
i.e n = 7 children
Hence, The Total number of children does Kunal have is 7 children . Answer
Answer:
7 Children = 4 Daughters and 3 Sons
Step-by-step explanation:
As per the question:-
Dhaval is Son and Deepa is Daughter (As it is clearly mentioned "he has brother while his sister Deepa")
Step 1 - Let the Son be = s and Daughters be = d
Step 2 - Statement 1 (dhaval has twice as many sisters as he has brother) - d= 2(s-1) ( we will put -1 for Dhaval)
Sol = d = 2(s-1)
d = 2s - 2
2s - d = 2 ------------------------------- 1
Step 3 - Statement 2 (while his sister Deepa has the same no of sisters as she has brother) = s=d-1 ( we will put -1 for Deepa) ------- 2
Now putting 2nd in 1st
2 (d-1) -d = 2, we get d = 4 and s = 3
Hence, answer is 7!!
