Me – Algebra can help me to find out how many brothers and sisters do you have.
Student – How is that possible ? If I don’t tell you about my brothers & sisters, how can Algebra help you?
Me – That is the beauty of maths dear!! Ok, lets try it out.
Student – Ok.
Me – Please follow these 8 steps with me.
1. Think of the number of brothers you have.
2. Add 2 to this number.
3. Now multiply by 2
4. Now add 1
5. Now multiply by 5
6. Now add the number of Sisters you have
7. Now subtract 25 from it
8. Thats all. You must have got a 2 digit number. First digit is the number of brothers and the second digit is the number of sisters you have.
Student – Amazing !! How did you do that? I, too want to master Algebra.
Me – Sure. Here is the algebra behind this puzzle.
2. B + 2
3. 2B + 4
4. 2B + 5
5. 10B +25
6. 10B + 25 + S
7. 10B + S
8. Here you go !!
Student – Thank you teacher. I will also try to make puzzles using Algebra now.
Me – Well done !! To make it more challenging, think of a situation where the number of brothers and sisters, both are more than 10.
