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

**Problem**

**Problem**

3% of rice stored in a godown is pilfered and 5% of the rest goes bad. If 11058 quintals of the rice remains in good condition, what was the original amount stored?

- 11500 quintals
- 11800 quintals
- 12000 quintals
- 12500 quintals
- 1300 quintals

**The Usual Method**

Let the original quantity of rice stored in the godown = *x* quintals.

Hence, rice in good condition =

quintals.

**(Ans: 3)**

*Estimated Time to arrive at the answer = 45 seconds.*

**Using Technique**

[contentblock id=google-adsense-post]

Simply add 3% and 5%, we get 8%(-)

Approximately 8% of the rice is reduced from the original quantity. Note that the (-) sign indicates that the actual value will be slightly less than 8%.

8% of 11058 or 11000 (rounded) = 880. Add this to 11058, we get:

11058 + 880 = 11938. Thus the actual answer should be close to 11938. The only option satisfying this condition is option ‘3’.

**(Ans: 3)**

*Estimated Time to arrive at the answer = 15 seconds.*
