A is three years older than B who is thrice as old as C. The total of the ages of A, B and C is 59. How old is C?

OPtion

1) 24 years
2) 27 Years
3) 10 Years
4) 7 Years
5) 9 Years
6) 6 Years
7) 8 Years
8) 11 Years
9) 5 Years
10)None of these

Solution

Let’s assume Age of B be B years
Age of A = B+3
Age of C = B/3

Total age = B + 3 + B + B/3 = 59
Solving 7B/3 = 56
B = 24
C = B/3 = 24/3 = 8 years

Option 7)

Correct Option: 7 Best Solution (13)

Venkatesh kadali   7 years AGO

let C age is X
then B age is : 3X
and A age is : 3X+3
so sum of the ages of A,B,C =59
i.e 3X+3+3X+X=59
7X=56
X=8
so Age of C is 8
so ansewer option 7

Let the ages of A,B,C = 3x+3,3x,x which satisfies the condition.
3x+3+3x+x= 7x+3=59
7x=59-3=56
x=8years
Hence the age of C is 8years.
Right option is 7

Assume age of c=x years.
Then age of B=3X years
A=3+3X
Total age
3X+3+3X+x=59years
7x=56years
X=8years
So,age of C=8 years
Option (7) is correct.

Devendra Marghade   7 years AGO

B=3C and A=B+3=3C+3
Sum of present ages of A,B & C=(3C+3)+3C+C=59
=> 7C=56 or C=8

Let C's age =x
B's age = 3 times age of C= 3*x = 3x
A's age = 3x+3
A.T.Q,
3x+3+3x+x=59
7x+3= 59
x= 56/7
or, x= 8
