Solution : (e) :
Answer :
According to statement 1 : we have G = V = K,
According to statement 2 : we have V + K + A = 32 and A = V + K.
Now using both the equations:
Putting V + K = A in V + K + A = 32, we have :
A + A = 32
or 2A = 32, A = 16 years
Now, V + K = A
V + K = 16 and V = K from statement 1.
Now, 2V = 16, V = 8 = K.
Thus G is also equal to 8, according to statement 1.
