Any Perfect Square other than that of 0 and 1 is always a multiple of 3 or one more than a multiple of 3

Any Perfect Square other than that of 0 and 1 is always a multiple of 4 or one more than a multiple of 4

But Together isn't true always!

Shortcut #3

When we want to keep a product constant and one of the variable is increasing by n/p; its corresponding counterpart has to decrease by n/(p + n)

Ex: In a rectangle, length increases by 40%. By what percentage must breadth reduce so as to keep the area constant.

If area is constant and length increased by 40% = 2/5,

That means breadth should decrease by 2/(2 + 5) = 2/7 = 28.57%
