Explanation :
1) Answer: B
Number of literate population in Karnataka = 240000 * 5/8 = 150000
Number of illiterate population in Karnataka = 3/8 * 240000 = 90000
Number of male literate population in Karnataka = 5/8 * 72000 = 45000
Number of male illiterate population in Karnataka = 3/8 * 72000 = 27000
Required ratio = (150000 – 45000):(90000 – 27000)
= 105000:63000
= 5:3
2) Answer: C
Required total = 150/100 * 48000 + 125/100 * 184000
= 72000 + 230000
= 302000
3) Answer: C
Required average = (168000 + 184000 + 130000 + 216000 + 144000)/5
= 842000/5
= 168400
4) Answer: A
Required percentage = ((230000 + 300000)/2)/((200000 + 192000)/2) * 100
= ((530000/2)/(392000/2)) * 100
= 265000/196000 * 100
= 135%
5) Answer: D
Required difference = (216000 + 144000)/2 - (72000 + 48000 + 84000)/3
= (360000/2) – (204000/3)
= 180000 – 68000
= 112000
