Case Based Questions Test: Arithmetic Progressions - Question 3

Read the following text and answer the following questions on the basis of the same: Amit has a packet of Candies. It consists of 288 candies. He arranges the candies in a way that first row contains 3 candies, second row has 5 and third row has 7 and so on.

Q. How many rows are there?

Detailed Solution for Case Based Questions Test: Arithmetic Progressions - Question 3
The A.P. is 3, 5, 7, ................

⇒ 288 = n [3+(n−1)]

⇒ 288 = n2 + 2n

⇒ n2 + 2n − 288 = 0

⇒ n2 + 18n − 16n − 288 = 0

⇒ n(n + 18) − 16(n + 18) = 0

⇒ (n + 18)(n − 16) = 0

⇒ n = 16

Case Based Questions Test: Arithmetic Progressions - Question 10

Read the following text and answer the following questions on the basis of the same: In a potato race, a bucket is placed at the starting point, which is 5 m from the first potato and the other potatoes are placed 3 m apart in a straight line. There are ten potatoes in the line (see figures).

A competitor starts from the bucket, picks up the nearest potato, runs back with it, drops it in the bucket, runs back to pick up the next potato, runs to the bucket to drop it in, and she continues in the same way until all the potatoes are dropped in the bucket.

Q. What is the total distance run by the competitor?
Detailed Solution for Case Based Questions Test: Arithmetic Progressions - Question 10
The sequence of distances is 10, 16, 22, 28.

a2 – a1 = 16 – 10 = 6

a3 – a2 = 22 – 16 = 6

a4 – a3 = 28 – 22 = 6

a2 – a1 = a3 – a2 = a2 – a1

∴ The sequence forms an A.P.

Here a = 10, d = a2 – a1= 16 – 10 = 6, n = 10

Now, total distance run by competitor = S10

= 5[20 + 9 × 6]

= 5[20 + 54]

= 5 × 74

= 370 m

Case Based Questions Test: Arithmetic Progressions - Question 11

Read the following text and answer the following questions.

A manufacturer of TV sets produced 600 sets in the third year and 700 sets in the seventh year, assuming that the production increases uniformly by a fixed number every year.

Q. Find the production in the 10th year.

Detailed Solution for Case Based Questions Test: Arithmetic Progressions - Question 11
a10 = a + 9d = 550 + 9(25) = 550 + 225 = 775
Case Based Questions Test: Arithmetic Progressions - Question 12

Read the following text and answer the following questions.

A manufacturer of TV sets produced 600 sets in the third year and 700 sets in the seventh year, assuming that the production increases uniformly by a fixed number every year.

Q. What is the difference between the productions of two consecutive years?

Detailed Solution for Case Based Questions Test: Arithmetic Progressions - Question 12

The given problem describes that the production of TV sets increases uniformly by a fixed number every year. We are provided with the following information:

  • Production in the third year = 600 sets
  • Production in the seventh year = 700 sets

Let's assume the production in the first year is P1​, and the production increases by a constant difference ddd every year.

  • Production in the third year, P3=P1+2d=600
  • Production in the seventh year, P7=P1+6d=700

Now, we can solve for ddd by subtracting the two equations:

P7−P3=(P1+6d)−(P1+2d)=700−600

4d=100

d=100/4 = 25

So, the difference between the productions of two consecutive years is 25​.

Case Based Questions Test: Arithmetic Progressions - Question 13

Read the following text and answer the following questions.

A manufacturer of TV sets produced 600 sets in the third year and 700 sets in the seventh year, assuming that the production increases uniformly by a fixed number every year.

Q. Find the production in the first year?

Detailed Solution for Case Based Questions Test: Arithmetic Progressions - Question 13
Let a be the production in first year and d be the difference between the productions of two consecutive years.

a3 = a + 2d = 600 …(i)

a7 = a + 6d = 700 …(ii)

Subtracting (i) from (ii),

d = 25

Put value of d in (i), we get

a = 550

Case Based Questions Test: Arithmetic Progressions - Question 14

Read the following text and answer the following questions.

A manufacturer of TV sets produced 600 sets in the third year and 700 sets in the seventh year, assuming that the production increases uniformly by a fixed number every year.

Q. Find the total production in the first 7 years.

Detailed Solution for Case Based Questions Test: Arithmetic Progressions - Question 14

a+2d=600
a+6d=700
4d=100
d=25
so a+2x25=600
a+50=600
a=550

Case Based Questions Test: Arithmetic Progressions - Question 15

Read the following text and answer the following questions.

A manufacturer of TV sets produced 600 sets in the third year and 700 sets in the seventh year, assuming that the production increases uniformly by a fixed number every year.

Q. If they produced 600 sets in the year 2010. Then in what years their production will be 1000?

Detailed Solution for Case Based Questions Test: Arithmetic Progressions - Question 15

As given in the question, the production increases uniformly , and the company produced 600 sets in the third year and 700 sets in 7th year
So, production increase in 4 years = 100
Production increase per year = 25 sets
Now the question says, initially if the company has produced 600 sets and we have to calculate when the company will produce 1000 sets.
We can use AP in this concept in which we just have to calculate n .

  • an = a + (n – 1)d
  • 1000 = 600 +(n – 1) 25
  • 400 = (n – 1) 25
  • 16 = (n – 1)
  • 17 = n
  • Therefore , in 17 years the production will be 1000 units.
