Age Practice Set – Mathematics

 1 . Present ages of Sameer and Anand are in the ratio of 5 : 4 respectively. Three years hence, the ratio of their ages will become 11 : 9 respectively. What is Anand’s present age in years? समीर और आनंद की वर्तमान उम्र क्रमश: 5: 4 के अनुपात में हैं। तीन साल इसलिए, उनकी उम्र का अनुपात क्रमशः 11: 9 हो जाएगा। वर्षों में आनंद की वर्तमान उम्र क्या है? A. 24 B. 27 C. 40 D. Data inadequate Answer: Option A Explanation: Let the present ages of Sameer and Anand be 5x years and 4x years respectively. Then 5x + 3/4𝑥 + 3 = 11/9 9 (5x + 3) = 11 (4x + 3) x = 6 Anand’s present age = 4x = 24 years View Answer

 2 . The ratio between the present ages of P and Q is 5 : 7 respectively. If the difference between Q’s present age and P’s age after 6 years is 2, what is the total of P’s and Q’s present ages? वर्तमान में पी और क्यू के बीच अनुपात 5: 7 है। यदि क्यू की वर्तमान उम्र और पी की उम्र 6 साल के बाद का अंतर 2 है, तो पी और क्यू की वर्तमान आयु का कुल क्या है? A. 46 years B. 48 years C. 52 years D. 56 years Answer: Option B Explanation:Let the present ages of P and Q be 5x years and 7x years respectively. Then 7x – (5x + 6) = 2 2x = 8 x = 4 Required sum = 5x + 7x = 12x = 12 × 4 = 48 years View Answer

 3 . Eighteen years ago, a father was three times as old as his son. Now the father is only twice as old as his son. Then the sum of the present ages of the son and the father is अठारह साल पहले, एक पिता अपने बेटे के रूप में तीन गुना पुराना था। अब पिता अपने बेटे के रूप में केवल दोगुना पुराना है। फिर बेटे और पिता की वर्तमान उम्र का योग है A. 54 years B. 72 years C. 105 years D. 108 years Answer: Option D Explanation:Let the present ages of Father and Son be 2x years and x years respectively. Then (2x – 18) = 3 (x – 18) 2x – 18 = 3x – 54 x = 54 – 18 x = 36 Required sum = (2x + x) = 3x = 3 × 36 = 108 years View Answer

 4 . My brother is 3 years elder to me. My father was 28 years of age when my sister was born while my mother was 26 years of age when I was born. If my sister was 4 years of age when my brother was born, then, what was the age of my father and mother respectively when my brother was born? मेरे भाई मेरे लिए 3 साल बड़े हैं। मेरे पिता की उम्र 28 वर्ष थी जब मेरी बहन पैदा हुई थी, जबकि मेरी मां 26 वर्ष की थी जब मेरा जन्म हुआ था। अगर मेरी बहन 4 साल की थी जब मेरे भाई का जन्म हुआ, तो मेरे भाई का जन्म होने पर क्रमशः मेरे पिता और मां की उम्र क्या थी? A. 32 yrs., 23 yrs. B. 32 yrs., 29 yrs. C. 35 yrs., 29 yrs. D. 35 yrs., 33 yrs. Answer: Option A Explanation:Clearly, my mother was born 3 years before I was born and 4 years after my sister was born. So, father’s age when = (28 + 4) Brother was born = 32 years Mother’s age when brother was born = (26 – 3) = 23 years View Answer

 5 . A person was asked to state his age in years. His reply was, “Take my age three years hence, multiply it by 3 and then subtract three times my age three years ago and you will know how old I am.” What was the age of the person? एक व्यक्ति को अपनी उम्र साल में बताने के लिए कहा गया था। उनका जवाब था, “मेरी उम्र तीन साल ले लो, इसलिए इसे 3 से गुणा करें और फिर तीन साल पहले मेरी उम्र तीन गुना घटाएं और आपको पता चलेगा कि मैं कितना पुराना हूं।” व्यक्ति की उम्र क्या थी? A. 14 years B. 18 years C. 20 years D. 32 years Answer: Option B Explanation:Let the present ages of the person be x years. Then = 3 (x – 3) – 3 (x – 3) x = (3x + 9) – (3x – 9) x = 18 View Answer

 6 . A father said to his son, “I was as old as you are at present at the time of your birth.” If the father’s age is 38 years now, the son’s age five years back was एक पिता ने अपने बेटे से कहा, “मैं आपके जन्म के समय वर्तमान में उतना पुराना था।” अगर पिता की उम्र 38 वर्ष है, तो पांच साल पहले बेटे की उम्र थी A. 14 years B. 19 years C. 33 years D. 38 years Answer: Option A Explanation:Let the son’s present age be x years. Then (38 – x) = x 2x = 38 x = 19 Therefore son’s age 5 years back = (19 – 5) = 14 years View Answer
