Total number of cars and autorickshaws in a garage is 23. The total number of wheels of these vehicles is 81. (a) if the number of cars is taken as x, then what is the total number of wheels of cars? (b) Find the number of cars and autorickshaws
Answers
Answer:
(a) 48 (b) 12 , 11
Step-by-step explanation:
(a) if the N0, of cars be x , then N0, of autoricksaws be 23 - x
given that, 4 x + 3 (23 - x) = 81
4 x + 69 - 3 x = 81
x = 81 - 69
= 12
∴ total number of wheels of cars = 12 x 4
= 48
(b) Number of cars = x
= 12
No, of rickshaws = 23 - x
= 23 - 12
= 11
Answer:
3 cars and 20 autos
Step-by-step explanation:
given information =
no. of cars and autos =23
no. of wheels =81
(a) no. of cars =x
wheels =81x-4x
=77x
(b) no. of cars=x
no.of autos =23x-x
wheels =83
cars have 4 wheels and autos have 3 wheels
therefore x+23x-x=4x+3x
24x=8x
8x =24 x
x=3cars and 20 autos
