The diagram represents an “adding machine” where numbers are added at each stage in a sequence.
In the first step, we add the top two numbers, which are 2 and 0. The result is 2 + 0 = 2.
Next, we move to the bottom two numbers, which are 1 and 3. Adding these together gives 1 + 3 = 4.
Finally, we add the two results from the previous steps. We take the sum from step 1 (2) and the sum from step 2 (4). Adding these gives 2 + 4 = 6.
Thus, the final result is 6.
Diana’s cube is a 3x3x3 cube, which contains 27 smaller cubes in total, as calculated by 3 × 3 × 3 = 27.
From the image, we can see that Nathalie’s cube uses 20 smaller cubes. To determine how many cubes Nathalie still needs, we subtract the number of cubes she already has from the total number of cubes in the 3x3x3 cube:
27 − 20 = 7.
So, Nathalie needs 7 more cubes to complete her cube.
The diagram shows that ⅛ of the total distance is equal to 100 meters. To find the total distance, we need to multiply 100 by 8, since 8 × 1/8 = 1, which represents the whole distance.
Therefore, the total real distance between Mara’s and Bunica’s houses is:
100 × 8 = 800 meters.
Nick starts at point A, facing upward (north), and needs to reach point B, following the restriction of only turning right. To navigate the training ground efficiently, he must plan a route with the smallest number of right turns.
Nick first moves straight north and makes his first right turn to head east. He continues straight and then makes a second right turn to head south. Moving forward, he takes a third right turn to go west. Finally, he makes a fourth right turn to head north, reaching point B.
By following this route, Nick completes the journey with exactly four right turns, which is the minimum number required. This ensures he reaches his destination without breaking the rules or taking unnecessary detours.
Answer: (B) 4.
Ann, Bob, and Chris currently have a combined age of 31 years. In three years, each of them will age by 3 years, resulting in a total increase of:
3 × 3 = 9 years (since there are three people).
Adding this increase to their current total age gives:
31 + 9 = 40 years.
So, in three years, their combined age will be 40 years.
The Gurukan family consists of three daughters, and each daughter has two brothers. Since all the daughters share the same two brothers, there are no extra siblings to count. Additionally, the family includes two parents who are shared by all the children.
Adding up all the members:
3 daughters,
2 brothers,
2 parents.
This gives a total of 3+2+2=7 family members. The key detail is that the two brothers are shared among the daughters, so they are not counted multiple times.
Answer: (B) 7.
