A painter can paint 2 small rooms and a balcony in 50 hours. If a small room takes twice as long to paint as a balcony, how long will it take him to paint 1 small room plus 3 balconies?

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
