Which of the following statement is true?

(I) Ratio of female visitors in the month of Jan, 2017 and Feb, 2017 together to the male visitor in the month of October, 2016 and December, 2016 is 145 : 87.

(II) Average of the total number of the male visitors in the given months of 2017 is 60,000

(III) Difference between the adult female visitors and child female visitors in the month of January, 2017 is 17,500

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.
