Out of a salary of Rs. 13,500, I keep 1/3 as savings. Of the remaining money, I spend 50% on food and 20% on house rent. How much do I spend on food and house rent?
उत्तर
Total salary = ₹ 13500
My savings = `1/3` of ₹ 13500 = ₹ 4500
Remaining salary = ₹ 13500 − 4500
= ₹ 9000
Amount spent on food = 50% of ₹ 9000
= Rs. `50/100xx9000` = ₹ 4500
Amount spent on rent = 20% of ₹ 9000
= `₹20/100xx9000` = ₹ 1800
Total amount spent on food and rent
= ₹ 4500 + ₹ 1800 = ₹ 6300

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.
A label on a sunscreen with SPF 30 claims that the sunscreen blocks about 97% of harmful UV rays. Assuming the SPF factor is accurate, is this claim true? Explain.
