 A.1,4
 B.2,1
 C.3,4
 D.4,2

Explanation : 1 turtle in each tank = 1 turtle too many 2 turtles in each tank = 1 tank too many Using one of the better known heuristic to solve this question Before that, we know that: 2 turtles in each tank = 1 tank too many 2 turtles in each tank = 2 turtles short First, find the difference in the number of turtles in the two scenarios: First scenario = 1 turtle too many Second scenario = 2 turtles short Difference in turtles = 1  ( 2) Difference in turtles = 3 Second, find the difference in the distribution of turtles: First scenario = 1 turtle each tank Second scenario = 2 turtles each tank Difference in turtle = 2  1 Difference in turtles = 1 Find the number of tanks: Number of tanks = 3 ÷ 1 Number of tanks = 3 Find the number of turtles: Using the first scenario, there was one turtle too many Number of tanks = 3 Number of turtles = 3 + 1 Number of turtles = 4 There are 4 turtles and 3 tanks.
