(or)
The difference of difference is, (1*2), (2*3), (3*4), (4*5)
The answer is, 462
Direction (6-10) :
6) Answer: c)
The total male population in state P and R together
= > 60*(7/12) + 36*(3/4)
= > 35 + 27 = 62 lakhs
The total female population in state Q and T together
= > 45*(4/9) + 72*(1/2)
= > 20 + 36 = 56 lakhs
Required difference = 62 – 56 = 6 lakhs
7) Answer: a)
The above poverty line population in state R
= > 36*(60/100)
The below poverty line population in state S
= > 50*(34/100)
Required ratio = [36*(60/100)]: [50*(34/100)]
= > 108: 85
8) Answer: d)
The total number of female population in state P, R and S together
= > 60*(5/12) + 36*(1/4) + 50*(3/5)
= > 25 + 9 + 30 = 64 lakhs
9) Answer: b)
The above poverty line population in state P and Q together
= > 60*(75/100) + 45*(70/100)
= > 45 + 31.5 = 76.5 lakhs
Total population in state S = 50 lakhs
Required % = (76.5/50)*100 = 153 %
10) Answer: c)
The below poverty line population in state R and T together
= > 36*(40/100) + 72*(20/100)
= > 14.4 + 14.4 = 28.8 lakhs
The total male population in state Q and S together
= > 45*(5/9) + 50*(2/5)
= > 25 + 20 = 45 lakhs
Required % = [(45 – 28.8)/45]*100 = 36 % less
