Question

in set of number 1,2,3,4,5,7,8,10,11,12 what percentage of numbers are odd number and what percentage of numbers are less then 8

Answer 1

Total numbers = 10
No. of odd no.=5
Percentage if odd no.= No. of odd no × 100 ÷ Total no.s
                                  = 5 × 100 ÷ 10
                                  = 500÷10
                                  =50%

No. less than 8 = 6
Percentage of no. less than 8 = No. less than 8  × 100 ÷ Total no.s
                                               = 6 × 100 ÷10
                                               = 600 ÷ 10
                                               = 60%
