1. First, number the fig of your brothers successful your mind. 2. Add 2 to that number.
3. Now multiply the resulting fig with 2.
4. Add 1 to it.
5. Then multiply it by 5.
6. Add the fig of your sisters to it.
7. Deduct 25 from the successful resulting number.
8. Now you volition get a fig with 2 digits.
The archetypal digit represents the fig of brothers portion the 2nd represents the fig of sisters. *Shocked??..*
The tenth digit is the fig of your member siblings and the azygous digit onthe close manus broadside denotes the fig of sisters .
It is revealed that we are adding the fig of sisters .Adding and deducting 25 volition person nil effect. So. 1 tin easy accidental the close manus digit is the fig of sister siblings Even if. you person nary brothers 25 volition beryllium the reply and if you deduct 25 the remaining digit volition amusement the fig of sisters
If you have10 brothers and nil sisters
125 volition beryllium the answer. if you person nary siblings astatine each you volition get 25 and deduct 25, 0 volition beryllium the reply We find for each member the reply increases by 10 that is to 35,45,55
While we are shocked with the correctness of the answer,we besides observe the following.
If x is the fig of brothers and y is the fig of sisters, the equation aft the calculations successful steps 1-7 is 10x+y.
It volition enactment but lone arsenic agelong arsenic y is little than 10. When y is adjacent to oregon greater than 10, the equation goes haywire (say 1 member and 10 sisters volition pb to a people of 20 which is incorrect).
I felt that the occupation composer should person intelligibly stipulated that the fig of brothers and sisters should beryllium successful azygous digit only.
Some Maths stalwarts constituent retired that measurement 8 of the question itself says
"Now you volition get a fig with 2 digits.
The archetypal digit represents the fig of brothers portion the 2nd represents the fig of sisters. "
This itself is simply a tacit mode of telling that the siblings should beryllium successful azygous digit only.
But if I person 3 brothers and 10 sisters past I get the reply arsenic 40,a 2 digit fig that is wholly wrong.
The occupation finds a spot successful Google also.
Even present I consciousness that the question is incorrect.The information should beryllium circumstantial .
What bash you accidental friends?
