Break-Up of Goods Exported in a Year

What is the ratio of the total exports of computers in 2015 and 2017 to the total exports of cosmetics in 2015 and 2018?

36 : 25

Total export of computer in 2015 & 2017 = \(\frac{24 }{100}\) × 400 + \(\frac{24 }{100}\) × 500

=96 + 120

= 216

Total export of cosmetics in 2015 & 2018 = \(\frac{15 }{100}\) × 400 + \(\frac{15 }{100}\) × 600

= 60 + 90

= 150

Required ratio ,  216  :  150
