What is the difference between the total constructions (constructed, demolished and redeveloped) in city Q and city T?

Production of rice by different states over the years:
A ? 1500 + 1480 + 1620 + 1700 + 1540 + 1650 = 9490 tonnes
B ? 1250 + 1190 + 1400 + 1450 + 1320 + 1380 = 7990 tonnes
C ? 1160 + 1190 + 1310 + 1300 + 1340 +1360 = 7660 tonnes
D ? 1520 + 1500 + 1480 + 1590 + 1630 + 1580 = 9300 tonnes
E ? 1440 + 1350 + 1430 + 1280 + 1380 + 1400 = 8280 tonnes
F ? 1600 + 1620 + 1510 + 1610 + 1580 + 1590 = 9510 tonnes
Hence, the state C produced the lowest quantity of rice.

Total number of employees in 2003 = Employees of (Production deptt.+ Sales deptt.+ Procurement deptt.+ Administration & Accounts deptt. + Research & Development deptt.)
Total number of employees in 2003 =150 + 25 + 50 + 45 + 75 = 345
Total number of employees in 2005 = (Production deptt.+ Sales deptt.+ Procurement deptt.+ Administration & Accounts deptt.+ Research & Development deptt.)
Total number of employees in 2005 = 450 + 65 + 30 + 90+ 73 = 708
Hence, it was the year 2005 when total number of employees in the factory became nearly double the total number of employees working in the factory during 2003.

Required difference = Number of B type tyres in 1994 - Number of B type tyres in 1995
Required difference = ( 27.5 ? 22.5 ) Million = 5 Million = 5000000.

Given :- Total population in 1988 = 146947 , increase = 11630
Total population in 1989 = Total population in 1988 + increase = 146947 + 11630 = 158577
? The number of children in 1989 = Total population in 1989 ? ( Total number of men in 1989 + Total number of women in 1989 )
= 158577 ? (70391 + 62516) = 25670.

Increase in taxation in between the financial years 2005-06 and 2006-07
= Rs. (2400 - 1730) = RS. 670 crores

Average of the total taxation during the years = total taxation for all the years / 6.
Average of the total taxation during the years = 600 + 725 + 1260 + 1730 + 2400 + 625 = 7390/6 = 1231.7 crores

Let the 7 consecutive whole numbers be (n ± 3), (n ± 2), (n ± 1), n.
Now i we consider Statement I alone
Product of these 7 integers = 702800
Since 702800 = 2⁴ 5² (251)(7), it cannot be the product of 7 consecutive whole numbers. Hence I alone is insufficient.
Now if we consider Statement II alone
Given that their sum = 105 = 7n or n = 15 and then 7 consecutive integers are 12, 13, 14, 15, 16, 17, 18 So, II alone is sufficient.

Since sum is 360 hence P + Q + R + S = 360
From statement I alone we will get P = (Q + R + S)/3 from this we can find the value of P hence statement I alone is sufficient enough.
From statement II alone we can not find the value of P.
