D
Literate population in City E in the year 2008

= 60 ×  50  = 30 lakh
100

Literate population in City E in the year 2012

= 50 ×  70  = 35 lakh
100

∴   Reqd% =  (35 – 30)  × 100 = 16.67%
30


Hence, option D is correct.

Total Literate population in 2012 = 72 + 55 + 78 + 95 + 70 = 370

Total literate population in 2012
 
= 55% of 72 + 50% of 55 + 35% of 78 + 55% of 95 + 50% of 70 
 
= 39.6 + 36 + 27.3 + 52.25 + 35
 
= 190.15 lakh
 
Total illiterate population in 2012 = 370 – 190.15 = 179.85 lakh = 1.7985 crore
