The Deep Dive
Calculating percentages is like supercharging your math skills! For example, to find \( 10\% \) of Rs 50, simply move the decimal one place to the left: \( 50 \times 0.10 = Rs 5 \). Easy-peasy! Similarly, \( 20\% \) of Rs 80 can be calculated as \( 80 \times 0.20 = Rs 16 \). Now, let’s amp up your problem-solving skills! A common trick is to first convert percentages into fractions. For instance, \( 25\% \) is the same as \( \frac{1}{4} \). So for \( 25\% \) of 40 students, simply divide 40 by 4 to get \( 10 \) students. Apply this same logic as you tackle the other percentages, and watch those numbers add up like magic!
