Question

The school hiking club had a car wash on Saturday and Sunday. The students washed 30% of the cars on Saturday. If they washed 24 cars on Saturday, how many cars did they wash on both days?

Answer 1

Let the total number of cars washed on both days be M.

Given that, the students washed 30% of the cars on Saturday.

Means, 30% of total cars.

→ 30% of M

→ 30/100 × M

→ 3M/10

Also given that, the students washed 24 cars on Saturday.

Let us assume that the students washed N number of cars.

So, N = 24

N = 3M/10

Substitute value of N above

→ 24 = 3M/10

→ 24*10 = 3M

→ 240 = 3M

→ 240/3 = M

→ 80 = M

Therefore,

They washed total 80 cars on both days.

Answer 2

QUESTION :-

The school hiking club had a car wash on Saturday and Sunday. The students washed 30% of the cars on Saturday. If they washed 24 cars on Saturday, how many cars did they wash on both days?

➠ let the numbers of cars washed on both days be R.

➠ cars washed on Saturday is 30% of total car washed. ( given)

➠ So, car washed on Saturday,

➠ n = 30% of n= 3/10R.

➠ °.° cars washed on Saturday is given as 24.

➠ since, n = 24

➠ 3/10 R = 24

➠ 3 R = 24 × 10

➠ R = 240/3

➠ R = 80

SO, 80 cars were washed on both days.
