Question

Cagayan Valley 1997 = 5, 2007 = 13. CAR 1997 = 3, 2007 = 9. MIMAROPA 1997 = 2, 2007 = 6. CARAGA 1997 = 1, 2007 =2. Davao 1997 = 0, 2007 = 2. Zamboanga 1997 = 5, 2007 = 5. Choices are: a. Cagayan Valley b. CAR, MIMAROPA, CARAGA. c. CAR, MIMAROPA, Cagayan Valley, Davao, CARAGA d. CAR, MIMAROPA, Davao, CARAGA e. CAR, MIMAROPA, Zamboanga, CARAGA

Answer 1

 

Similar to a previous question with the same figures and names.

Cagayan Valley gained 8 cities,

Car gained 6,

Mimaropa gained 4,

Caraga gained 1,

Davao gained 2,

Zamboanga gained none.

So the least cities gained were in Zamboanga (0) and Caraga (1).

All other regions (Cagayan Valley, Car, Mimaropa, Davao) gained at least two additional cities.

In order from most gained to least gained: Cagayan Valley, Car, Mimaropa, Davao, Caraga, Zamboanga.

Answer c contains all the regions that made gains. Only Zamboanga is missing because it made no gains.
