(a) 32 years
(b) 40 years
(c) 38 years
(d) 42 years
(e) 46 years

Ans- Average of mother and her three children=𝑠𝑢𝑚 𝑜𝑓 𝑎𝑔𝑒 𝑜𝑓 𝑚𝑜𝑡ℎ𝑒𝑟 𝑎𝑛𝑑 ℎ𝑒𝑟 3 𝑐ℎ𝑖𝑙𝑑𝑟𝑒𝑛/4
Sum of age of mother and her three children=19× 4 = 76 𝑦𝑒𝑎𝑟𝑠
Similarly, sum of her three children= 3× 10 = 30 years
Mother age’s=76-30=46years

Q2. Twenty years ago, the age of father and his son in the ratio of 8:3. Presently, the father is only 127th times of his son then find out the present age of son?

(a) 28 years
(b) 32 years
(c) 35 years
(d) 21 years
(e) none of these

Ans- Let the present age of son =7𝑥
Then the present age of father=12/7× 7𝑥=12𝑥
𝑥 = 5
Present age of son =7𝑥=7× 5 = 35 𝑦𝑒𝑎𝑟𝑠

Q3. The present age of A and B in the ratio 7:12. 20 years ago, the age difference between Aand B was 15 years. Then find out the sum of present ages of A and B?

(a) 57 years
(b) 53 years
(c) 76 years
(d) 38 years
(e) 45 years
S3. Ans (a)
Sol.Let present age of A =7𝑥 years
And present age of B =12𝑥 years
Age difference always remains same
12𝑥 − 7𝑥 = 15
𝑥 = 3
So, sum of present age of A and B =7𝑥 + 12𝑥 = 19𝑥 = 19 × 3 = 57 years

Q4. 8 years ago, the ratio of the ages of Rachana and Archana was 4 : 3. If the ratio of their present ages is 6 : 5 respectively, what is the ratio of the sum and difference of their present ages?

(b) 11 : 4
(c) 11 : 1
(d) 11 : 3
(e) None of these

Sol. Rachana′s age/Archana′s age=6x/5x
8 years ago the ratio of their age =4/3
20𝑥 − 32 = 18𝑥 − 24
2𝑥 = 8
𝑥 = 4
Rachana’s age = 24 years
Archana’s age = 20 years
Required ratio = 44/4=11/1
