Given : the average age of mr and mrs sinha at the time of their marriage in 1972 was 23 years. on the occassion of theri anniversary in 1976 they observed that the average age of their familh had come down by 4 years compares to their average age at the time of their marriage
To find : Age of Son Vicky in 1980
Solution:
the average age of mr and mrs sinha at the time of their marriage in 1972 was 23 years.
=> Their total age = 2 * 23 = 46 Years
in 1976 average age = 23 - 4 = 19 years
Total age = 3 * 19 = 57 Years
1976 - 1972 = 4
Age of Mr & mrs sinha = 46 + 4 + 4 = 54 Years
=> Age of Son = 57 - 54 = 3 Years
Age of Son Vicky in 1980 = 3 + (1980 - 1976) = 3 + 4 = 7
Age of Vicky in 1980 = 7 Years
