Mathematics Logic Brain Cracking Problems with Answers and Explanations


Mathematics Logic Brain Cracking Problems
Mathematics Equations are very much fun to solve. However if we twist these mathematical equations then the fun of solving it with logic gets double. Here are some math equations which has been twisted so that result is different from the expected answer. However each equation in every brain teaser below follow some logical twist. One has to find this logical twist to these math equations and has to calculate the final equation, so that it follow the same logic as the previous equations.
Answers to these equations along with explanations are given below. However please do post your answers with logical conclusions in the comment box of this post.

Following are the answers of these Mathematics Logic Brain Cracking Problems
1. Given Mathematical Equation is A+B=C
Logically deducted Equation is 3*(A+B)=C
So answer is 3*24 = 72





2. Given Mathematical Equation is A=B
Logically deducted Equation is A*(A+3)=B
So answer is 2*(2+3) = 10





3. Given Mathematical Equation is A+B=CD
Logically deducted Equation is A*B=C and A+B=D
So answer is (7*3)(7+3) = 2110





4. Given Mathematical Equation is A+B=C
Logically deducted Equation is  A+(A*B)=C
So answer is 8+(8+11) = 96





5. Given Mathematical Equation is A+B=C
Logically deducted Equation is 3*(A+B)=C
So answer is 3*(4+20) = 72
