Question

The e-waste increases by 15 % every year, according to the study report. There was around 9 crore tonnes of e-waste in 2014. Then how many tonnes of e-waste will be there in 2020.

Answer 1

E-waste in 2014 – 9 crore tonnes

Rate of increase = 15 %

The E-waste in 2020 = 9 × (1 + \(\frac{15}{100}\))⁶

= 9 × (\(\frac{115}{100}\))⁶

= 20. 82 crore tonnes
