Question 96

A bulb manufacturer found that 19% of the bulbs were repaired in the overall production. If the number of unbleached bulbs is 2025, find the number of defective bulbs.

Solution

% of non defective bulbs = $$100-19=81\%\equiv2025$$

=> Number of defective products = $$19\%\equiv\frac{2025}{81}\times19$$

= $$25\times19=475$$

=> Ans - (A)
