Q1. A neighbourhood taxi flags a boarding charge of Rs 40 and then bills Rs 12 for each kilometre. Reading its fare-against-distance line, what does a 7 km ride cost?
- A.Rs 124
- B.Rs 40
- C.Rs 84
- D.Rs 112
Answer: A. Rs 124
The straight line is y = 40 + 12x. Put x = 7: y = 40 + 12*7 = 40 + 84 = 124.
Q2. An electrician asks Rs 150 as a visit fee and Rs 90 for every hour of work. From the bill-versus-hours line, what is the charge for a job lasting 4 hours?
- A.Rs 360
- B.Rs 420
- C.Rs 510
- D.Rs 150
Answer: C. Rs 510
The straight line is y = 150 + 90x. Put x = 4: y = 150 + 90*4 = 150 + 360 = 510.
Q3. A gym membership has a joining fee of Rs 800 plus Rs 600 for each month attended. On the total-paid line, what has a member paid after 6 months?
- A.Rs 800
- B.Rs 3600
- C.Rs 4400
- D.Rs 3800
Answer: C. Rs 4400
The straight line is y = 800 + 600x. Put x = 6: y = 800 + 600*6 = 800 + 3600 = 4400.
