On Sunday 845 people went to the Zoo. On Monday only 169 people went. What is the per cent decrease in the people visiting the zoo on Monday?
उत्तर
It is given that on Sunday, 845 people went to the zoo and on Monday, 169 people went.
Decrease in the number of people = 845 − 169 = 676
Percentage decrease = `("Decrease in the number of people"/"Number of people who went to zoo on sunday")%`
= `(676/845 xx 100)%`
= 80%

Sunscreens block harmful ultraviolet (UV) rays produced by the sun. Each sunscreen has a Sun Protection Factor (SPF) that tells you how many minutes you can stay in the sun before you receive one minute of burning UV rays. For example, if you apply sunscreen with SPF 15, you get 1 minute of UV rays for every 15 minutes you stay in the sun.
Suppose a sunscreen allows 25% of the sun’s UV rays.
