Data Sufficiency Data Sufficiency - Base Level 3

To find the code for 'come' we need to have two statements which have one common code word and 'come' as the common word, which is there in I and III.

From I, II and III, we conclude that all P, Q, T, and U are children of X.Of these, to Q and U are male while R and T are female. But the sex of P cannot be determined.

Observing I, II and III, we find that similar letters have similar code symbols at the corresponding places in the code. So, this is direct-coding.

Thus, to find the code for DATE, we need the code for D which can be obtained from I only ( i. e. $ ) and the codes for A, T and E which can be obtained either from II or III @, # and % respectively).

From II, we conclude that in a class of 40, Deepak rank 23rd from the bottom i. e. 18th from the top.

From I and II, we find that Suman is 3 ranks below 18th rank from the top i. e.she rank 21st from the top.

From Ii and III, we find that Suman is 3 rank above 23rd rank from the bottom i. e. she ranks 20th from the bottom or 21st from the top.

From I, we have : P > D, P > N, T > P > i. e. T > P > D > N >

or T > P > N > D .......(i)

From II, we have : R > Q , T > R i. e. T > R > Q .........(ii)

From III, we have : T > Q, R > Q ............ (iii)

Clearly, from (i) and (ii), we conclude that T is taller than each one of P, N, D, R and Q. So, T is the tallest.

Clearly, from I and III, we conclude that T is to the North-West of R.

From the given statement, the descending order of heights is : _, Q, _, S, _.

From II, we have the order : _, Q, R, S, _. Thus, R is in the middle.

From III, we have the order : P, Q, _, S, _. But, according to I, T is not the shortest.

So, R is the shortest. Thus, we have the order : P, Q, T, S, R. So, T is in the middle.

From I, we conclude that the girl is either Kunal's or his brother's wife. But, according to II, Kunal has no siblings.

So, from both I and II, we conclude that the girl is Kunal's wife.

From III, we find that the girl is the only daughter-in -law of Kunal's mother i. e. she is Kunal's wife.

From I, the order is : E, B, C or C, B, E.

From II, the order is : E, B.

From III, the order is : A, D, E.

Combining the above three, we get the order as : A, D, E, B, C. Clearly, E is sitting in the middle.

From II , we know that Gopal's brother was bron in 1982.

From III, we find we find Gopal's brother was 8 years younger to him i. e. Gopal's was bron in 1974.

From I, we find that Sanjay is 6 years older than Gopal. Thus, Sanjay was bron in 1968.
