[GMAT math practice question]
If C=P(1+r/100)^n where C is the capital, P is the principal in 2001, and r is the compound interest rate after n years, by what percent did the capital increase from n years later to n+5 years later?
1) n=5
2) r=5
=>
Forget conventional ways of solving math questions. In DS, VA (Variable Approach) method is the easiest and quickest way to find the answer without actually solving the problem. Remember that equal number of variables and independent equations ensures
