Answer 1

Answer:

number of auto rickshaws are 11

number of cars are 12

Step-by-step explanation:

a) number of wheels in cars are 4x because each car has 4 wheels

b) let no. of auto rickshaws be y

x+y=23

y=23-x

4x+3y=81            (auto rickshaws have 3 wheels)

4x+3(23-x)=81

4x+69-3x=81

x=81-69=12

y=23-12=11
