A foreign tourist hired a guide for his trip to Agra and Delhi.
He admired the beauty of Taj at Agra
and asked how many years it took to build.

"12 years" - The guide replied.

"12 Years!! You Indians are so lazy" - The tourist said ,
"In my country, this could have been done in 4 years"

Next day he went to visit the Red Fort.
He admired it's architecture
and asked how many years it took to build.

"21" - The guide replied.

"21 Years!! You Indians are very slow" - The tourist said ,
"In my country, this could have been done in 7 years"

In this manner he said that every building he liked
could have been built in one third of the time.

Finally they reached Qutub Meenar at Delhi.
The tourist asked what it was and how long it took to build.
The guide replied - "I don't know, because it was not there ,
