Question

Can you please help with this?

 

At an art exhibition, there were a total of 77 paintings and posters. 1/4 of the paintings and 14 of the posters were sold. After that, there were an equal number of paintings and posters left. How many more posters than paintings were there at fist?

Thanks!

Answer

1 – 1/4 = 3/4
3 units left of paintings
Since equal number of paintings and posters left, 
3 units left of posters, same unit size. 
3u + 3u + 1u + 14 = 77
7u = 63
u = 9
number of paintings = 4u
number of posters = 3u + 14
difference = (3u +14) – (4u)
= 14 – u
=14 – 9
= 5

Number of posters more than paintings = 5
