C Correct answer
Explanation

S = 2K + 7. (S+3) = (K+3) + 19 => S = K + 19. 2K + 7 = K + 19 => K = 12. S = 12 + 19 = 31.

Multiple choice

Ram's age is $\frac {1}{3}rd$ of his father's age. Ram's father's age will be 12 years more than twice of Shyam's age after 10 years. If Shyam's eighth birthday was celebrated 3 years before, then what is Ram's age at present
  1. $14$ yrs.
  2. $16$ yrs.
  3. $11$ yrs.
  4. $13$ yrs.

A Correct answer
Explanation

Shyam's 8th birthday was 3 years ago, so he is 8 + 3 = 11. In 10 years, Shyam will be 21. Father's age in 10 years = 2(21) + 12 = 54. Father's current age = 54 - 10 = 44. Ram's age = 1/3 * 44 = 14.66. The answer 14 is the closest integer.

Multiple choice

Five years ago, the age of a father was thrice the age of his son. In five years time, the age of the father will be twice the age of his son at that time. Find their present ages.
  1. Present age of father is $60$ years and present age of son is $20$ years
  2. Present age of father is $35$ years and present age of son is $15$ years
  3. Present age of father is $65$ years and present age of son is $25$ years
  4. Present age of father is $50$ years and present age of son is $15$ years

B Correct answer
Explanation

Let F and S be current ages. (F-5) = 3(S-5) => F = 3S - 10. (F+5) = 2(S+5) => F = 2S + 5. Equating: 3S - 10 = 2S + 5 => S = 15. Then F = 2(15) + 5 = 35.

Multiple choice

Ten years ago father was $12$ times as old as his son at that time and $10$ years hence he will be twice as old as his son. Find their present ages.
  1. $55$ years, $24$ years
  2. $34$ years, $12$ years
  3. $48$ years, $19$ years
  4. $42$ years, $18$ years
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Let F, S be present ages. (F-10) = 12(S-10) => F-10 = 12S - 120 => F = 12S - 110. (F+10) = 2(S+10) => F+10 = 2S + 20 => F = 2S + 10. 12S - 110 = 2S + 10 => 10S = 120 => S = 12. F = 2(12) + 10 = 34.

Multiple choice

Five years ago, A's age was four times the age of B. Five years hence, A's age will be twice the age of B. Find their present ages.
  1. Present age of $A = 29$ years and that of $B = 11$ years
  2. Present age of $A = 25$ years and that of $B = 10$ years
  3. Present age of $A = 65$ years and that of $B = 20$ years
  4. Present age of $A = 40$ years and that of $B = 10$ years
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Let A and B be current ages. (A-5) = 4(B-5) => A - 4B = -15. (A+5) = 2(B+5) => A - 2B = 5. Subtracting equations: 2B = 20, so B = 10. Then A = 25.
