    Solution

    (I) Number of female visitors in Jan, 2017 = 1,36,000×5/8 = 85,000 Number of female visitors in Feb, 2017 = 1,30,000 ×6/13 = 60, 000 Total number of female visitor in Jan, 2017 and Feb, 2017 = 85,000 + 60,000 = 1,45,000 Number of male visitors in October, 2016 = 65,000 ×6/13 = 30,000 Number of male visitors in December, 2016 = 95,000×3/5 = 57,000 Total number of male visitor in October, 2016 and December, 2016 = 30,000 + 57,000 = 87,000 [if gte msEquation 12]>∴ [if !msEquation]-->[if gte vml 1]> [if !vml]-->[endif]--> [endif]--> Required ratio = 145 : 87 Hence, statement 1 is correct. (II) Number of male visitors in January, 2017 = 1,36,000×3/8= 51,000 Number of male visitors in February, 2017 = 1,30,000×7/13 = 70,000 Average of the total number of the male visitor in 2017 =(51000+70000)/2= 60,500 Hence, statement II is incorrect. (III) In January, 2017, Number of female visitors in Jan, 2017 = 1,36,000×5/8 = 85,000 Number of adult female visitors = 40%×5/8× 1,36,000 = 34,000 Number of child female visitors = 85,000 – 34,000 = 51,000 [if gte msEquation 12]>∴ [if !msEquation]-->[if gte vml 1]> [if !vml]-->[endif]--> [endif]--> Required difference = 51,000 – 34,000 = 17,000 Hence, statement III is also incorrect.
