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

8000 was the original number of dolls

Answer 2

Answer:

Let the total production = 100

Defective dolls = 20/100*100 =20

Good dolls =100-20 =80

Now 25% of 80 is defective

Now assuming 80 =100

25% out of 100

Left over dolls= 4800

100-25=75

75/100*x= 4800

x =4800*100/75 (this x is 80 as 100)

x=6400

Now total dolls produced

= 80/100*x =6400

x= 6400*100/80 (here x =total)

x =8000
