1.	Find: (i) 22% of 120 (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» (i) 22% of 120 \(=\frac{120\times22}{100}=\frac{364}{10}\)=26.40 (ii) 25% of Rs 1000 \(=\frac{1000\times25}{100}\)=Rs.250 (iii) 25% of 10 kg \(=\frac{10\times25}{100}=\frac{250}{100}\)=2.5 kg (iv) 16.5% of 5000 metre \(=\frac{5000\times16.5}{100}\)=\({16.5\times50}\)=825 m (v) 135% of 80 cm \(=\frac{80\times135}{100}=\frac{135\times4}{5}\)=108 cm (vi) 2.5% of 10000 ml \(\frac{10000\times2.5}{100}\)=250 ml

Find: (i) 22% of 120 (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»

(i) 22% of 120

\(=\frac{120\times22}{100}=\frac{364}{10}\)=26.40

(ii) 25% of Rs 1000

\(=\frac{1000\times25}{100}\)=Rs.250

(iii) 25% of 10 kg

\(=\frac{10\times25}{100}=\frac{250}{100}\)=2.5 kg

(iv) 16.5% of 5000 metre

\(=\frac{5000\times16.5}{100}\)=\({16.5\times50}\)=825 m

(v) 135% of 80 cm

\(=\frac{80\times135}{100}=\frac{135\times4}{5}\)=108 cm

(vi) 2.5% of 10000 ml

\(\frac{10000\times2.5}{100}\)=250 ml
