Question
Lenin was also given 7 trays of eggs to examine. One tray has 10 eggs, the eggs did Lenin examine in total is?
- 70
- 80
- 90
- 60
Hint:
enin was given 7 trays of eggs. One tray has 10 eggs , to find the total no of eggs that Lenin examine is to just multiply both the given term . It says 1 tray have 10 eggs then 7 tray has how much. Easy multiplication would give you the solution.
The correct answer is: 70
Here , we have to find the total number of eggs Lenin examine.
Firstly, The given eggs in one tray is 10
Now , And total trays Lenin examine is 7,
So we can write that,
1 tray = 10 eggs
1 x 7 trays = ( 10 x 7 ) eggs [total trays are 7 so we multiplied both side by 7]
7 trays = 70 eggs
Therefore the total eggs examined by Lenin is 70
The correct answer is 70 (option (a)).

After their vacation, they figured out that the farm was divided into 5 sections and each section has an area of 100 acres. Find the total area of the farm?
You are given the 5 section and each section area are same so you can multiply one by 5 to find area in easy way. Also remember area can be different of each section in some different question so you can easily apply the same method to solve the question, just add the all section of area and that would be your answer.
