(2) The population of City Z first exceeded 1,000,000 in 1930, and the population of City X first exceeded 1,000,000 37 years after the population of City Z first exceeded 1,000,000.


Confusing One!

(1) The population of City Y first exceeded 1,000,000 in 1963, and the population of City X first exceeded 1,000,000 41⁄2 years after the population of City Y first exceeded 1,000,000.
City X exceeded 1,000,000 population after 41/2 = 20 years 6 months of 1963

Since, we do not know in which month of 1963 does City Y touched 1,000,000 population, 2 possible outcomes
Case 1: If Population of City Y touched 1,000,000 in 1st half of 1963, City X touches 1,000,000 in <1963.5 + 20.5 = 1983
Case 2: If Population of City Y touched 1,000,000 in 2nd half of 1963, City X touches 1,000,000 in >1963.5 + 20.5 = 1984

Insufficient

(2) The population of City Z first exceeded 1,000,000 in 1930, and the population of City X first exceeded 1,000,000 37 years after the population of City Z first exceeded 1,000,000.
Only 1 case, since its exactly after 37 years

Case 1: If Population of City Z touched 1,000,000 in 1930, City X touches 1,000,000 in 1930 + 37 = 1967

Sufficient

IMO Option B

Pls Hit kudos if you like the solution
