Answer:
50 hours
Step-by-step explanation:
Given that :
Painter can paint 2 small rooms and a balcony on 50 hours
Small room takes twice as long to paint as a balcony
Let :
Time taken to paint balcony = t
Time taken to paint small room = 2t
t + 2(2t) = 50
t + 4t = 50
5t = 50
t = 10
how long will it take him to paint 1 small room plus 3 balconies?
1 small room = 2t
3 balconies = 3t
2t + 3t = 5t
5(10) = 50 hours
