Answer 2

4.1

Cost of 22ltrs of petrol = Rs300

Cost of 1ltr of petrol = 300/22

= 150/11

= Rs13.63

4.2

distance = 330km = d

speed = 110km/hr = s

time = d/s

= 330/110

= 33/11

= 3hrs

4.3

SI = principal amount × rate of interest × time

$= 2000 \times \frac{9}{100} \times 4$

$= 20 \times 9 \times 4$

$= 720$

Amount = Principal + SI

= 2000 + 720

= Rs2720
