A wholesale trader sold Rs 20 lakh worth of cloth this year. If the sale of cloth increases at a rate of 2% per year, how much will the sale be after three years?

Answer 1

GiVen:-

• Cloth sold at worth 20 lakh.

• Sale of this cloth increases 2% per year.

To Find:-

• Sale after three years.

AnSwer:-

Sale after 3 years would be :-

$\longmapsto \sf \: \: 20 {( 1 + \dfrac{2}{100} )}^{3} lakh \\ \\ \longmapsto \sf \: \:20 {( \frac{100 + 2}{100})}^{3}lakh \: \\ \\ \longmapsto \sf \: \: 20 {( \frac{102}{100})}^{3}lakh\\ \\ \longmapsto \sf \: \:20 \times {(1.02)}^{3} lakh \\ \\ \longmapsto \sf \: \:20 \times 1.061208 \: lakh \\ \\ \longmapsto \sf \: \:21.22416 \: lakh \\ \\ \longmapsto \sf \: \:21.22416 \times {10}^{6} \: Rs \\ \\ \longmapsto \sf \: \:21224160 \: Rs$

So, after 3 years sale will be at Rs 21224160.
