माना की वह राशि x है|
(i) x का 35% = 280
\(x \times \frac{35}{100} = 280\)
\(x = 280 \times \frac{100}{35}\)
\(x = 800\)
(ii) \(\frac{3}{5} \)% = 90
x का \(\frac{3}{5} \)% = 90
\(x \times \cfrac{\cfrac{3}{5}}{100} = 90\)
\(x \times \frac{3}{500} = 90\)
\(x = 90 \times \frac{500}{3}\)
\(x = 15000\)
(iii) 0.25% = 600
x का 0.25% = 600
\(x \times \frac{0.25}{100} = 600\)
\(x = 600 \times \frac{100}{0.25}\)
\(x = 240000\)
