Q:

If the present ages of a father and his son are 48 years and 28.8 years old respectively, then the father can say to his son, "I was ......... of your present age when you were born".

A) half B) two-third

Answer & Explanation Answer: B) two-third

Explanation:

The present age of Father (f) = 48 and present age of son (s) = 28.8
The age of father at his sons birth is 48 - 28.8 = 19.2
Therefore the age of father was 2/3rd of his son's age at the time of his sons birth

Its absolute electrode potential is estimated to be 4.44 ± 0.02 V at 25 °C, but to form a basis for comparison with all other electrode reactions, hydrogen's standard electrode potential (E0) is declared to be zero volts only at 298.
