Direction: The given table shows the shirts produced in 4 years by a company. Read the given table carefully and answer the given questions. Table: Year | No. of Shirts produced (in lakh) | % of shirts failed the quality test — 2014: 3.2, 2.5%; 2015: 4.0, 2.25%; 2016: 2.8, 1.25%; 2017: 3.6, 1.25%. Note: Shirts which failed the quality test were not sold. In 2015, 10% of the shirts that passed the quality test remained unsold. How many remain unsold?

Explanation

Calculation: Shirts produced in year 2015 = 4 Lakh. Percent of shirts passed the quality test = 100 – 2.25 = 97.75%. No. of shirts remain unsold after passing quality test = 400000 × 97.75% × 10% ⇒ 39,100. Now, shirts which didn't pass the quality test also remain unsold which will be equal to = 400000 × 2.25% ⇒ 9000 ⇒ Total number of shirts which remain unsold = 39,100 + 9000 = 48,100. ∴ Required number of shirts which remain unsold is 48,100. Mistake Points: We will also include the shirts that failed the quality test as they also remained unsold.
