On a certain day, 38 patients came to the clinic. Out of all the patients, 23 were having dental examination, 18 dental fillings and 8 tooth extraction. The number of patients
who underwent for dental examination and tooth extraction was one less then the
number of patients did dental examination and dental fillings. No patient was given
dental fillings and tooth extraction service.

1) Find the number of patients who came for tooth extraction only

2) Find the number of patients who came for dental examination and fillings​

step-by-step explanation:

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

radha is now 5 years old

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !

it would be 0.18 because when the other choices are converted they equal those two numbers.   hope this !
