Required percentage = (8820 × 100) ⁄ 144000 %= 6.125
Correct Option: A
Number of men who can read and write = 150000 × (98 ÷ 100) =147000
Number of men and women who can read and write =294000 × (53 ÷ 100) =155820
Number of women who can read and write 155820 - 147000 = 8820
Thus, out of 144000 women 8820 can read and write.
Required percentage = (8820 × 100) ⁄ 144000 %= 6.125
