Total exports of cosmetics in four years is approximately what percent less than the total exports of Garments and Jewellery in 2015 and 2018?
Answer & explanation
Correct answer: option 2
Total export of cosmetics in all 4 years = \(\frac{15 }{100}\) × 400 + \(\frac{15}{100}\) × 650 + \(\frac{15}{100}\) × 500 + \(\frac{15 }{100}\) × 600
= 60 + 97.5 + 75 + 90
= 322.5
total exports of Garments and Jewellery in 2015 and 2018
= \(\frac{28 }{100}\) × 400 + \(\frac{28 }{100}\) × 600 + \(\frac{8 }{100}\) × 400 + \(\frac{8 }{100}\) × 600
= 112 + 168 + 32 + 48
= 360
Required percentage = \(\frac{360 - 322.5 }{360}\) × 400
= \(\frac{37.5 }{360}\) × 400
= 10.4%
