Question:medium

Kiran’s brother is 5 years older to her. Her father was 30 years old when Kiran’s sister was born, while her mother was 28 years old when Kiran was born. If Kiran’s sister was 2 years old when her brother was born, what was the age of their father when Kiran’s brother was born?

Translate all statements into fixed \emph{age gaps}; add or subtract gaps to move between births, then shift the known parent’s age accordingly.

The Correct Option is A

Approach Solution - 1

Step 1: Set Kiran's birth year as year 0. Since the brother is 5 years older than Kiran, the brother was born in year \( -5 \).

Step 2: Since the sister was 2 years old when the brother was born, the sister is 2 years older than the brother, so the sister was born in year \( -5-2=-7 \).

Step 3: The father was 30 years old when the sister was born, in year \( -7 \). By the brother's birth, in year \( -5 \), 2 more years have passed, so the father's age at that point is \( 30+2=32 \).
\[ \boxed{32} \]

Approach Solution -2

We can assign concrete calendar years to check this cleanly. Suppose Kiran was born in the year 2000. Since the brother is 5 years older, he was born in 1995, and since the sister is 2 years older than the brother, she was born in 1993. We can test each option by treating it as the father's birth year offset and checking whether it puts him at exactly 30 years old in 1993.

  1. 32: If the father was 32 in 1995, he was born in \( 1995-32=1963 \), making his age in 1993 equal to \( 1993-1963=30 \), matching the given fact exactly.
  2. 34: If the father was 34 in 1995, he was born in \( 1995-34=1961 \), making his age in 1993 equal to \( 1993-1961=32 \), not the given 30.
  3. 37: If the father was 37 in 1995, he was born in \( 1995-37=1958 \), making his age in 1993 equal to \( 1993-1958=35 \), not 30.
  4. 30: If the father was 30 in 1995, he was born in \( 1995-30=1965 \), making his age in 1993 equal to \( 1993-1965=28 \), not 30.

Fixing concrete birth years for each sibling shows that only a father's age of 32 at the brother's birth is consistent with him being exactly 30 two years earlier, at the sister's birth.

Therefore, the correct answer is 32.

Read the passage and answer the question.

Passage (extract): The work which Gandhiji had taken up was not only regarding the achievement of political freedom but also the establishment of a new social order based on truth and non-violence, unity and peace, equality and universal brotherhood and maximum freedom for all. A new order cannot be established without radically changing the mind and attitude of men towards property and, at some stage or the other, the 'haves' have to yield place to the 'have-nots'. We have seen, in our time, attempts to achieve a kind of egalitarian society and the picture of it after it was achieved. But this was done, by and large, through the use of physical force. It may even be that, like a gas kept confined within containers under great pressure, or water held back by a big dam, once the barrier breaks, the reaction will one day sweep back with a violence equal in extent and intensity to what was used to establish and maintain the outward egalitarian form. This enforced egalitarianism contains, in its bosom, the seed of its own destruction. If egalitarianism is to endure, it has to be based not on the possession of the maximum material goods by a few or by all but on voluntary, enlightened renunciation of those goods which cannot be shared by others or can be enjoyed only at the expense of others.

Passage (extract): The work which Gandhiji had taken up was not only regarding the achievement of political freedom but also the establishment of a new social order based on truth and non-violence, unity and peace, equality and universal brotherhood and maximum freedom for all. This unfinished part of his experiment was perhaps even more difficult to achieve than the achievement of political freedom. In the political struggle, the fight was against a foreign power and all one could do was either join it or wish it success and give it his/her moral support. In establishing a social order on this pattern, there was a strong possibility of a conflict arising between diverse groups and classes of our own people.

Passage (extract): In the political struggle, the fight was against a foreign power and all one could do was either join it or wish it success and give it his/her moral support. Experience shows that man values his possessions even more than his life because in the former he sees the means for perpetuation and survival of his descendants even after his body is reduced to ashes. We have seen, in our time, attempts to achieve a kind of egalitarian society and the picture of it after it was achieved. But this was done, by and large, through the use of physical force. This enforced egalitarianism contains, in its bosom, the seed of its own destruction. The root cause of class conflict is possessiveness or the acquisitive instinct.
