Answer 2

Answer:

18. 135km

19. Ravi bought the books with cheaper rate.

Step-by-step explanation:

18. Distance travelled by the car with 22litres of petrol = 198km

Distance travelled by the car with 1litre of petrol = 198 ÷ 22 = 9km

Distance travelled by the car with 15liters of petrol = 15 × 9 = 135 km

19. Cost of 15 notebooks bought by Ravi = 225

Cost of 1 notebook bought by Ravi =225÷15=15

Cost of 12 notebooks bought by Reema = 192

Cost of 1 notebook bought by Reema=192÷12=16

15<16

Ravi bought the books for cheaper rate.
