Question

20% of dolls produced in a factory were defective 25% of the remaining were damaged. If 4800 dolls were left over what was the original number of dolls.

Answer 1

Let, the number of dolls be x

$x \times \frac{80}{100} \times \frac{75}{100} = 4800 \\ \\ = > x = \frac{4800 \times 5}{3} \\ \\ = >x = 8000$

So, the original number of dolls will be 8000
