For GDP figure you are overstating Pak gdp and understating BD gdp. Pak gdp is 931 billion and BD gdp is 577 billion in ppp terms.

But BD is growing at 6-7 percent while Pakistan is 3-4 percent.So we can safely assume that BD gdp volume will overtake Pak whithin a dicade, despite having 40 million less people. GDP per capita wise BD will overtake Pak within 2-3 years maximum as per capita in BD is 1266 usd and Pakistan is 1427 usd.

But they are gone, so does the popularity of Pak team into the sewer.
