Understanding Imran's Age Problem

The video tutorial explains how to solve a problem involving Imran's age. It starts by introducing the problem, where Imran will be 11 times his current age in 40 years. The tutorial then sets up a linear equation using the variable x to represent Imran's current age. The equation is solved step-by-step, resulting in Imran being 4 years old. The solution is verified by checking that in 40 years, Imran will indeed be 44 years old, which is 11 times his current age.

What is the main problem discussed in the video?

• Finding the difference between Imran's age and his friend's age

• Calculating Imran's age in the past

• Calculating the average age of Imran's family

• Determining Imran's current age based on future age

What variable is used to represent Imran's current age?

• z

• y

• a

• x

How is Imran's age in 40 years expressed in terms of x?

• 40x

• x + 40

• 40 - x

• x - 40

What equation is set up to relate Imran's future age to his current age?

• x + 40 = 11

• 11x = 40

• x = 11x + 40

• x + 40 = 11x

What is the first step in solving the equation for x?

• Add x to both sides

• Multiply both sides by 11

• Subtract x from both sides

• Divide both sides by 11

After simplifying the equation, what expression do we get?

• 11x = 40

• x = 40

• 10x = 40

• x = 4

What is the final value of x, representing Imran's current age?

• 10 years

• 4 years

• 40 years

• 11 years

How do we verify the solution to the problem?

• By checking if 44 is 11 times 4

• By checking if 40 is 4 times 11

• By checking if 40 is 11 times 4

• By checking if 44 is 4 times 11

What is Imran's age in 40 years?

• 4 years

• 11 years

• 40 years

• 44 years

What mathematical operation is used to verify the solution?

• Multiplication

• Subtraction

• Addition

• Division
