Let x be the age of ishaan so the age of ben will be 12+x. the equation will become x=x+12
Going 3 years back, the age of ishaan was x-3 so that of ben would be x+12-3 before 3 years. at that time the age of ben was 4 times the age of ishaan. it means x+12-3(the age of ben)=4(x-3(the age of ishaan))
solving this equation, we get the answer x=7. this is the age of ishaan in the present.

Х years  -  Ishaan
(x + 12) years  -  Ben

3 years ago :
(х - 3) years  -  Ishaan
((x + 12) - 3) years  -  Ben
-------------------------------------------------
 (x + 12) - 3 = (x - 3) * 4
 x + 9 = 4x - 12
 x - 4x = - 12 - 9
 - 3x = - 21
 x = 21 : 3
 х = 7 years - is Ishaan now.

Please find attached the appropriate diagram to solve for this question

Complete Question :

The surface area of a given cone is 1,885.7143 square inches. What is the slant height?

Answer:

25 inches

Step-by-step explanation:

In the diagram, we are given the following information

Height of the cone = 20 inches

Radius of the cone = 15 inches.

The formula for the slant height of a cone represented by l =

l² = r² + h²

l = √(r² + h²)

l = √(15² + 20²)

l = √(225 + 400)

l = √625

l = 25 inches

Therefore, the slant height of this cone = 25 inches
