A carpenter makes custom chairs. He currently has 11 chairs in his showroom. If he can build 2 chairs each week, how many weeks will it take him to have a total of 23 chairs?

The correct answer is 6 weeks.

Step-by-step explanation:

The carpenter has currently 11 chairs in his show room.

He intend to have a total of 23 chairs.

Therefore the carpenter have to make 23 - 11 = 12 more chairs to meet his expectation of 23 chairs.

Rate at which he makes the chair = 2 chairs per week.

Number of weeks the carpenter would take to make 12 chairs = weeks = 6 weeks.

Thus the carpenter would take 6 more weeks to make 12 extra chairs and thus have a total of 23 chairs.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
