Can you solve this logic puzzle where age equals the sum of numbers?solution

This particular number-sum puzzle proved to be quite tricky. We encourage you to try to resolve this issue.

This is a tricky question to put into words, so let’s break it down step by step. In 2021, your age can be calculated by subtracting your birth year from 2021. Since you are not yet 100 years old, you were either born in the 1900s or the 2000s. Let’s first consider if you were born in the 1900s. Your age in 2021 minus 19ab, this must also be equal to the sum of the numbers in your birth year, which is 1 + 9 + a + b.

If you were born in the 2000s, your age is 2021 minus 20ab, and the sum of the numbers in your birth year is 2+a+b.

Now, let’s find solutions for each situation:

If you were born in the 1900s:

19ab = 1900 + 10a + b Simplify the left side: 2021 – (19ab) = 121 – 10a – b The right side: 1 + 9 + a + b = 10 + a + b Move the constant term to the left and the variable to Right side: 111 = 11a + 2b Since 111 is an odd number and 2b is always an even number, 11a must be an odd number. This means that a can only be 1, 3, 5, 7 or 9.

If 11a = 77, we get 111 – 77 = 34, but B cannot be 17. For other cases such as 11a = 55, 33 or 11, B will be larger.

The only feasible possibility is 11a = 99. In this case, you have 111 – 99 = 12, which equals 2b. Therefore, B = 6 and A = 9. This gives the 1996 solution.

If you were born in the 2000s:

20ab = 2000 + 10a + b Simplify the right-hand side: 2 + 0 = 2 So, 21 – 10a – b = 2 + a + b Rearrange the terms: 19 = 11a + 2b Since 19 is an odd number and 2b is even, so 11a It must be an odd number. The only possibility is 11a = 11, which means a = 1.

Then, 19 – 11 = 8, which is equal to 2b. Therefore, B = 4.

This gives two possible birth years: 1996 or 2014. You can check, if you were born in 1996, your age in 2021 will be 25, which is the sum of the numbers 1, 9, 9 and 6. If you were born in 2014, your age in 2021 is 7, which is the sum of the digits 2, 0, 1 and 4. So the answer is 1996 or 2014.

The calculation result is 88 ÷ 4 + 5 x 2 – 10 ÷ 5=?

To find out, remember the order of operations. Division and multiplication proceed from left to right: 88 ÷ 4 equals 22, and 10 ÷ 5 equals 2. The equation now becomes 22 + 5 x 2 – 2. Next, perform multiplication, addition and subtraction from left to right: 5 x 2 equals 10, and 22 + 10 equals 32. Therefore, the solution is 32.

Are you sure 180 ÷ 9 + 9 x 3 – 12 ÷ 3=?

Follow the order of operations as usual. Divide and multiply starting from left to right: 180 ÷ 9 equals 20, and 12 ÷ 3 equals 4. The equation now becomes 20 + 9 x 3 – 4. Next, perform multiplication, addition and subtraction from left to right: 9 x 3 equals 27, and 20 + 27 equals 47. Therefore, the solution is 47.
