Let us assume the age of B be P years then age of A will be P + 2 and age of C will be P/2 years.
Then according to question,
P + 2 + P + P/2 = 27
? P + P + P/2 = 27 - 2
? ( 2P + 2P + P)/2 = 25
? 5P = 25 x 2
&there; P = 50/5 = 10 years
Age of B will be 10 years.
F
Except option (c) rest all are perfect squares.
Except, `Plate', all two in number.
All other terms are used to denote the size.
15/20 x 5/4 x 2/3 x 8/5 = 1
