On sunday 1/16 people who visit were senior citizens, 3/16 were infants, 3/8 were children and 3/8 were adults, how many of each group visited the zoo on sunday

Out of total people visited the zoo on Sunday, 6.25% was senior citizen, 18.75% were infants, 35% were children and 35% were adult.

Step-by-step explanation:

let total number of people visited the group = x

so number of senior citizens = x * 1/16 = x/16

Percentage of senior citizens = (number of senior citizens : total number of people visited the group) * 100

= (x/16 : x) * 100 = 100/16 = 6.25%

number of infants = 3/16 * x = 3x/16

Percentage of infants = (number of infants : total number of people visited the group) * 100 = (3x/16 : x) * 100 = 300/16 = 18.75%

number of children = 3/8 * x = 3x/8

Percentage of children = (number of children : total number of people visited the group) * 100 = (3x/8 : x) * 100 = 300/8 = 37.5%

number of adults = 3/8 * x = 3x/8

Percentage of adults = (number of adults : total number of people visited the group) * 100 = (3x/8 : x) * 100 = 300/8 = 37.5%.

Hence we can conclude that Out of total people visited the zoo on Sunday, 6.25% was senior citizen, 18.75% were infants, 35% were children and 35% were adult.
