उत्तर

Number of students appeared in 2007 – 08 = 105332

Number of students appeared in 2008 – 09 = 116054

Number of students passed in 2007 – 08 = 88151

Number of students passed in 2008 – 09 = 103804

Passed percentage of students in 2007 – 08

= `("Number of students passed in"  2007 - 08)/("Number of students appeared in"  2007 - 08) xx 100`

= `88151/105332 xx 100`

= `8815100/105332`

= 83.68%

Passed percentage of students in 2008 – 09

= `("Number of students passed in"  2008 - 09)/("Number of students appeared in"  2008 - 09) xx 100`

= `103804/116054 xx 100`

= `10380400/116054`

= 89.44%

∴ Increase in percentage = 89.44 – 83.68 = 5.76%

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.

  2. Use your answer from Part (a) to calculate this sunscreen’s SPF. Explain how you found your answer.
