The three numbers in A.P are 5,12,19.

Step-by-step explanation:

Given : The sum of three numbers in AP is 36 and their product is 1140.

To find : The three numbers in AP ?

Solution :

Let the three numbers in A.P be (a-d), a and (a+d) respectively.

The sum of three numbers in AP is 36.

a-d+a+a+d=36

3a=36

a=\frac{36}{3}

a=12

Product of three numbers is 1140.

(a-d)\times(a)\times (a+d)=1140

a(a^2-d^2)=1140

12(12^2-d^2)=1140

144-d^2=\frac{1140}{12}

144-d^2=95

d^2=144-95

d^2=49

d=\sqrt{49}

d=\pm 7

When a=12 and d=7,

a-d=12-7=5

a=12

a+d=12+7=19

When a=12 and d=-7,

a-d=12-(-7)=19

a=12

a+d=12-7=5

Therefore, the three numbers in A.P are 5,12,19.
