Ages:<\/strong><\/p>\n\n\n\n

Problems on ages are usually based on concepts of ratio and proportions, percentages or averages.<\/p>\n\n\n\n

Basics:<\/p>\n\n\n\n

Let the present age of person \u2018A\u2019 be \u2018x\u2019 years<\/p>\n\n\n\n

Let the present age of person \u2018B\u2019 be \u2018y\u2019 years<\/p>\n\n\n\n

Then, age of \u2018A\u2019, 3 years ago from now = (x \u2013 3) years<\/p>\n\n\n\n

Age of \u2018B\u2019, 3 years ago from now = (y \u2013 3) years<\/p>\n\n\n\n

If it is said that, 3 years ago from now, the ratio of ages of \u2018A\u2019 and \u2018B\u2019 was p:q, respectively,<\/p>\n\n\n\n

We have, (x \u2013 3):(y \u2013 3) = p:q<\/p>\n\n\n\n

So, qx \u2013 3q = pq \u2013 3p<\/p>\n\n\n\n

Average of ages:<\/p>\n\n\n\n

If it is said that the average of present ages of \u2018A\u2019 and \u2018B\u2019 is \u2018p\u2019 years<\/p>\n\n\n\n

Then, sum of present age of \u2018A\u2019 and \u2018B\u2019 = p \u00d7 2 = \u20182p\u2019 years<\/p>\n\n\n\n

Let the present age of \u2018A\u2019 be \u2018x\u2019 years<\/p>\n\n\n\n

Then, present age of \u2018B\u2019 = (2p \u2013 x) years.<\/p>\n\n\n\n

Question 1:<\/strong> Rahul is 8 years older than Manish while Manish is 6 years older than Sonu. If ratio of age of Sonu to age of Rahul is 5:12, respectively, then what will be the age of Manish after 12 years?<\/p>\n\n\n\n

Solution 1: C)<\/strong><\/p>\n\n\n\n

Let, age of Sonu = \u2018x\u2019 years<\/p>\n\n\n\n

Age of Manish = \u2018x + 6\u2019 years<\/p>\n\n\n\n

Age of Rahul = \u2018x + 14\u2019 years<\/p>\n\n\n\n

So, x\/(x + 14) = 5\/12<\/p>\n\n\n\n

12x = 5x + 70<\/p>\n\n\n\n

7x = 70, x = 10<\/p>\n\n\n\n

Age of Manish after 12 years = x + 6 + 12 = 28 years<\/p>\n\n\n\n

Hence, option c.<\/p>\n\n\n\n

Solution 2: A)<\/strong><\/p>\n\n\n\n

Let the present ages of A and B are 4x years and 7x years respectively.<\/p>\n\n\n\n

Age of B after six years = 7x + 6 years<\/p>\n\n\n\n

Age of C after six years = (7x + 6) \u00d7 3\/2 = \u201810.5x + 9\u2019 years<\/p>\n\n\n\n

Present age of C = 10.5x + 9 \u2013 6 = \u201810.5x + 3\u2019 years<\/p>\n\n\n\n

According to question: 4x + 7x + 10.5x + 3 = 3 \u00d7 44<\/p>\n\n\n\n

21.5x + 3 = 132<\/p>\n\n\n\n

21.5x = 129, x = 6<\/p>\n\n\n\n

So the present age of A = 4 \u00d7 6 = 24 years<\/p>\n\n\n\n

Present age of C = 10.5 \u00d7 6 + 3 = 63 + 3 = 66 years<\/p>\n\n\n\n

So the desired difference = 66 \u2013 24 = 42 years<\/p>\n\n\n\n

Hence, option a.<\/p>\n\n\n\n

Solution 3: D)<\/strong><\/p>\n\n\n\n

Let, age of Rohit and Sohit be 6x years and 7x years, respectively.<\/p>\n\n\n\n

So, age of Mohit = 7x + 5 years<\/p>\n\n\n\n

According to question,<\/p>\n\n\n\n

6x + 7x + (7x + 5) = 35 \u00d7 3<\/p>\n\n\n\n

20x = 105 \u2013 5<\/p>\n\n\n\n

20x = 100, x = 5<\/p>\n\n\n\n

Therefore, age of Sohit = 5 \u00d7 7 = 35 years<\/p>\n\n\n\n

Hence, option d.<\/p>\n\n\n\n

Solution 4: D)<\/strong><\/p>\n\n\n\n

Let the present ages of Tarun and Miraj are 4x years and 5x years respectively<\/p>\n\n\n\n

Present age of Ashwani = 1.20 \u00d7 5x = 6x years<\/p>\n\n\n\n

Sum of the present ages of Tarun, Miraj and Ashwani = 4x + 5x + 6x = 30 \u00d7 3<\/p>\n\n\n\n

15x = 90, x = 6<\/p>\n\n\n\n

So the present age of Ashwani = 6 \u00d7 6 = 36 years<\/p>\n\n\n\n

Hence, option d.<\/p>\n\n\n\n

Solution 5: B)<\/strong><\/p>\n\n\n\n

Let the present ages of Shivani and Shilpa be 7x years and 5x years, respectively.<\/p>\n\n\n\n

Present age of Shipra = (5x \u2013 5) \u00d7 1.20 = 6x \u2013 6 years<\/p>\n\n\n\n

So according to question: 7x + 5x + 6x \u2013 6 = 3 \u00d7 (5x + 2)<\/p>\n\n\n\n

18x \u2013 6 = 15x + 6<\/p>\n\n\n\n

3x = 12, x = 4<\/p>\n\n\n\n

So the present age of Shivani = 7 \u00d7 4 = 28 years<\/p>\n\n\n\n

Hence, option b.<\/p>\n\n\n\n

Solution 6: C)<\/strong><\/p>\n\n\n\n

Let the present ages of Shweta, Pooja and Neha are 4x years, 3x years and 7x years respectively<\/p>\n\n\n\n

Present age of Reva = 1.40 \u00d7 (3x \u2013 4) = \u20184.2x \u2013 5.6\u2019 years<\/p>\n\n\n\n

According to question: 4x + 3x + 7x + 4.2x \u2013 5.6 = 35 \u00d7 4<\/p>\n\n\n\n

18.2x = 140 + 5.6<\/p>\n\n\n\n

18.2x = 145.6<\/p>\n\n\n\n

x = 8<\/p>\n\n\n\n

So the present age of Reva = 4.2 \u00d7 8 \u2013 5.6 = 28 years<\/p>\n\n\n\n

Hence, option c.<\/p>\n\n\n\n

Solution 7: A)<\/strong><\/p>\n\n\n\n

Let, age of Himanshu be x years,<\/p>\n\n\n\n

So, age of Sudit = (x + 8) years<\/p>\n\n\n\n

So, age of Mudit = (x \u2013 9) years<\/p>\n\n\n\n

According to question,<\/p>\n\n\n\n

(Sudit \u2013 3): (Mudit + 4) = 5: 3<\/p>\n\n\n\n

(x + 8 \u2013 3): (x \u2013 9 + 4) = 5: 3<\/p>\n\n\n\n

(x + 5): (x \u2013 5) = 5: 3<\/p>\n\n\n\n

3x + 15 = 5x \u2013 25<\/p>\n\n\n\n

2x = 40<\/p>\n\n\n\n

x = 20 years<\/p>\n\n\n\n

Therefore, age of Mudit = 20 \u2013 9 = 11 years<\/p>\n\n\n\n

Hence, option a.<\/p>\n\n\n\n

Solution 8: A)<\/strong><\/p>\n\n\n\n

Let the present ages of Manish and Ashwani are 5x years and 7x years respectively.<\/p>\n\n\n\n

So according to question: 1.32 \u00d7 (5x + 10) = 7x + 10<\/p>\n\n\n\n

6.6x + 13.2 = 7x + 10<\/p>\n\n\n\n

0.4x = 3.2, x = 8<\/p>\n\n\n\n

So the present ages of Manish and Ashwani are 40 years and 56 years respectively.<\/p>\n\n\n\n

Present average age of Manish and Ashwani = (40 + 56)\/2 = 48 years<\/p>\n\n\n\n

Hence, option a.<\/p>\n\n\n\n

Solution 9: C)<\/strong><\/p>\n\n\n\n

Ratio of the present ages of Rajan, Vishal and Abhishek = 3 \u00d7 2: 8: 11 = 6: 8: 11<\/p>\n\n\n\n

Let the present ages of Rajan, Vishal and Abhishek are 6x, 8x and 11x years respectively<\/p>\n\n\n\n

So according to question: (6x + 3)\/ (11x + 3) = 7\/12<\/p>\n\n\n\n

72x + 36 = 77x + 21<\/p>\n\n\n\n

5x = 15, x = 3<\/p>\n\n\n\n

So the present age of Vishal = 8 \u00d7 3 = 24 years<\/p>\n\n\n\n

Hence, option c.<\/p>\n\n\n\n

Solution 10: B)<\/strong><\/p>\n\n\n\n

Let, the present age of Veer be \u20183b\u2019 years<\/p>\n\n\n\n

Then, the present age of Dinesh = \u2018b\u2019 years<\/p>\n\n\n\n

So, (3b + 16)\/(b + 16) = 5\/3<\/p>\n\n\n\n

9b + 48 = 5b + 80<\/p>\n\n\n\n

4b = 32<\/p>\n\n\n\n

b = 8<\/p>\n\n\n\n

Therefore, the present age of Kartik = 19 + 8 = 27 years.<\/p>\n\n\n\n

Hence, option b.<\/p>\n\n\n\n
