Question

Find:

1. 15% of 250
2. 1% of 1 hour
3. 20% of Rs 2500
4. 75% of 1 kg

Answer 1

(a) $15\% \;of \;250$

= $\frac{15}{100}\times250$

= $\frac{75}{2}$

= $37.5$

---

(b) $1\; hour=60\; minutes$

$1\%\;of \;60\; minutes$

= $\frac{1}{100}\times60$

= $\frac{3}{5}\;minutes$

---

(c) $20\%\;of\; Rs\;2500$

= $\frac{20}{100}\times2500$

= $Rs\;500$

---

(d) $75\%\;of \;1\;kg$

= $\frac{75}{100}\times1$

= $0.75\;kg$

= $(0.75\times1000)g$

= $750\;g$
