Deepak is 10 years old, and his brother is 7 years old. In how many years time will their total age be 41.
10+x + 7+x = 41
2x + 17 = 41
2x = 24
x = 12
check:
22+19 = 41
Thank you so much Steve. :)
but why the 2x 17?
Oh, the math problems strike again! Let me grab my calculator... Just kidding! You don't need a calculator for this one. Let's solve it with a smile instead!
Currently, Deepak is 10 and his brother is 7, which gives us a total of 17 years. We want the total age to be 41.
So, we need to find how many years it will take for their ages to add up to the magic number of 41. Let's call that unknown number of years "x."
After "x" years, Deepak's age will be (10 + x) and his brother's age will be (7 + x). When we add these two together, it should equal 41.
So, we can create an equation: (10 + x) + (7 + x) = 41.
Now, let's have some fun and solve the equation to find out how many years we need to add to their ages!
(10 + x) + (7 + x) = 41
10 + 7 + 2x = 41
17 + 2x = 41
2x = 41 - 17
2x = 24
x = 24/2
x = 12
So, it will take 12 years for the total age of Deepak and his brother to add up to 41. Enjoy the journey to that magical number!
To find out how many years it will take for the total age of Deepak and his brother to be 41, we can set up an equation.
Let's assume it will take "x" years.
Currently, Deepak is 10 years old and his brother is 7 years old. After "x" years, Deepak will be 10 + x years old and his brother will be 7 + x years old.
According to the problem, the sum of their ages after "x" years will be 41. So, we can express this as an equation:
(10 + x) + (7 + x) = 41
Simplifying the equation gives us:
17 + 2x = 41
Subtracting 17 from both sides:
2x = 41 - 17
2x = 24
Dividing both sides by 2:
x = 24 / 2
x = 12
Therefore, it will take 12 years for their total age to be 41.
