Practice Questions Case Study Based from Chapter Quadratic Equations (Launched by Board)

CBSE Class 10 Maths paper which is scheduled for 2nd June, 2021, will embody questions primarily based on case research. That is for the primary time that the Maths paper could have case research questions. For college kids to not have any downside in fixing these new sort of questions, the board has supplied a query financial institution primarily based on case research. All these questions are fairly helpful to arrange for the upcoming board examination.

Now we have supplied beneath the questions for CBSE Class 10 Maths Chapter 4 – Quadratic Equations. All of the questions are supplied with solutions. College students should apply all of the case research primarily based questions to arrange effectively for his or her Maths examination.

Case Study Questions for Class 10 Maths Chapter 4 – Quadratic Equations

CASE STUDY 1:

Raj and Ajay are very shut pals. Each the households resolve to go to Ranikhet by their very own vehicles. Raj’s automotive travels at a velocity of x km/h whereas Ajay’s automotive travels 5 km/h sooner than Raj’s automotive. Raj took 4 hours greater than Ajay to finish the journey of 400 km.

1. What would be the distance coated by Ajay’s automotive in two hours?

a) 2(x + 5)km

b) (x – 5)km

c) 2(x + 10)km

d) (2x + 5)km

2. Which of the next quadratic equation describe the velocity of Raj’s automotive?

a) x2 – 5x – 500 = 0

b) x2 + 4x – 400 = 0

c) x2 + 5x – 500 = 0

d) x2 – 4x + 400 = 0

Reply: c) x2 + 5x – 500 = 0

3. What’s the velocity of Raj’s automotive?

a) 20 km/hour

b) 15 km/hour

c) 25 km/hour

d) 10 km/hour

4. How a lot time took Ajay to journey 400 km?

a) 20 hour

b) 40 hour

c) 25 hour

d) 16 hour

CASE STUDY 2:

The velocity of a motor boat is 20 km/hr. For protecting the space of 15 km the boat took 1 hour extra for upstream than downstream.

1. Let velocity of the stream be x km/hr. then velocity of the motorboat in upstream shall be

a) 20 km/hr

b) (20 + x) km/hr

c) (20 – x) km/hr

d) 2 km/hr

2. What’s the relation between velocity ,distance and time?

a) velocity = (distance )/time

b) distance = (velocity )/time

c) time = velocity x distance

d) velocity = distance x time

Reply: b) distance = (velocity )/time

3. Which is the right quadratic equation for the velocity of the present?

a) x2 + 30x − 200 = 0

b) x2 + 20x − 400 = 0

c) x2 + 30x − 400 = 0

d) x2 − 20x − 400 = 0

Reply: c) x2 + 30x − 400 = 0

4. What’s the velocity of present ?

a) 20 km/hour

b) 10 km/hour

c) 15 km/hour

d) 25 km/hour

5. How a lot time boat took in downstream?

a) 90 minute

b) 15 minute

c) 30 minute

d) 45 minute
