Here’s and example of a **SMART MATH** problem for **ARITHMETIC.**

**Problem**

**Problem**

Simplify 1/[1+1/{1+1/(1+1/4)}]

- 3/14
- 14/3
- 7/3
- 14/9
- 9/14

**The Usual Method**

[contentblock id=google-adsense-post]

First solving (…), we get: 1 + 1/4 = 5/4

Now Solving {…}, we get: 1+ 1/(5/4) = 9/5

Now Solving […], we get: 1 + 1/(9/5) = 14/9

Hence, answer is 1/(14/9) = 9/14

**(Ans: 5)**

*Estimated Time to arrive at the answer = 60 seconds*

**Using Technique**

[contentblock id=google-adsense-post]

Just solve the 1st level bracket i.e. (…), we get: 1 + 1/4 = 5/4.

5 > 4 or Numerator > Denominator

Also, since, there are three division operation further left, in the final answer, the Numerator < Denominator. This eliminates options ‘2’, ‘3’ and ‘4’.

Also, note that if in the first level of operation, we get the numerator and denominator as 5 and 4 respectively, and that further operations involve addition, the final answer will have a value greater than 5 and 4. This eliminates option ‘1’. Hence ‘5’ is the final answer.

**(Ans: 5)**

*Estimated Time to arrive at the answer = 10 seconds*
