(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
