(ii) 25% of Rs 1000
(iii) 25% of 10 kg
(iv) 16.5% of 5000 metre
(v) 135% of 80 cm
(vi) 2.5% of 10000 ml

Answer 1

$$\begin{gathered} \left(\mathrm{i}\right)22\%\mathrm{of}120=\frac{22}{100}\times 120 \\ =26.4 \\ \left(\mathrm{ii}\right)25\%\mathrm{of}1000=\frac{25}{100}\times 1000 \\ =250 \\ \left(\mathrm{iii}\right)25\%\mathrm{of}10\mathrm{kg}=\frac{25}{100}\times 10\mathrm{kg} \\ =\frac{25}{10}\mathrm{kg}=\frac{5}{2}\mathrm{kg} \\ =2.5\mathrm{kg} \\ \left(\mathrm{iv}\right)16.5\%\mathrm{of}5000\mathrm{m}=\frac{16.5}{100}\times 5000\mathrm{m} \\ =16.5\times 50\mathrm{m} \\ =825\mathrm{m} \\ \left(\mathrm{v}\right)135\%\mathrm{of}80\mathrm{cm}=\frac{135}{100}\times 80\mathrm{cm} \\ =\frac{135\times 8}{10}\mathrm{cm} \\ =108\mathrm{cm}=1.08\mathrm{m} \\ \left(\mathrm{vi}\right)2.5\%\mathrm{of}10000\mathrm{ml}=\frac{2.5}{100}\times 10000\mathrm{ml} \\ =250\mathrm{ml} \end{gathered}$$
