Answer 1

Answer:

ANSWER

Let original No. of doll =x

No. of defected dolls =10020x

Remaining dolls =10080x

Number of damaged dolls =25% of 10080x

                                              =10020x

No. of dolls leftover =4800

x−(10040x)=4800

              10060x=4800

                    x=8000

Original No. of dolls =8000
