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 =
Estimated Time to arrive at the answer = 45 seconds.
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’.
Estimated Time to arrive at the answer = 15 seconds.
