Arun and Vin each has some money, If Arun gives Rs.10 to Vin, then Vin will have twice the money left with Arun. But, if Vin gives Rs.10 to Arun, then they both have equal amount of money. How much money does Arun have?

Simplification is the process of replacing a mathematical expression with a simpler, equivalent one. Simplifying an expression involves writing it in its simplest form, without any more adding, subtracting, multiplying, or dividing. For example, the expression 4 + 6 + 5 can be simplified to 15.    Simplification can involve: Algebraic expressions, Boolean expressions, Fractions, Conjunction elimination.  Simplification can help to: Reduce a fraction by canceling it to the lowest common factor (LCM) for both the numerator and the denominator to its lowest term Reduce an algebraic...
