Concept: 1 Mark
Solution: 2 Marks
Let the required number of toys be n.
More the days, more is the number of toys. They are in direct proportion.
So, 4/4 = 8/t
t = 8
That is 8 toys can be made in 8 days by 4 toy-makers.
Again, more the toy-makers, more is the number of toys. They are also in direct proportion.
Toy-makers/ number of toys = 4/8 = 8/n
So, the number of toys made = 16
