Suppose my age = P years
My father's age = my age + 21 years = P + 21 years
Again After 12 years ,
2 ( my age + 12 ) = My father's age + 12
? 2 (P + 12) = (P + 21) + 12
? 2P + 24 = P + 33
? P = 33 ? 24 = 9 years
Hence , I am 9 years old now .
None of these
Except 'Z' , all others are vowels.
The series is ( + 7 x 1), (+ 6 x 2), (+ 5 x 3), (+ 4 x 4), (+ 3 x 5), (+ 2 x 6).
The wrong number is 32;
(9 + 6) x 2 = 15 x 2 = 30
These all are units of distance.
'OPINION' can be formed from ' COMPANIONSHIP' .
the pattern is ... man
