Q47

A class II mathematics teacher gives the following word problem on addition to the students to solve :
“A bag contains 4 mangoes and 6 more mangoes are added to it. How many total mangoes are there in the bag?”
This type of word problem belongs to which of the following structures of addition?

  1. (1) AugmentationCorrect answer
  2. (2) Segregation
  3. (3) Repeated addition
  4. (4) Aggregation

Solution.

CBSE answer: (1)

Answer: (1) Augmentation

  1. Augmentation means an existing quantity is increased by adding more to it.
  2. Here the bag already has 4 mangoes and 6 more are put in, so the 4 grows to 10.
  3. Aggregation is different: two separate groups are combined, such as 4 mangoes in one bag and 6 in another.

Trap: aggregation also gives 10, but the story has one set getting bigger, not two sets joined.
