Answer 2

5 painters

Step-by-step explanation:

given :

10 painters complete a work in 40 days

then how many painters complete the same work in 80 days

solution :

$formula mens X days X hours / work done$

$m1 *d1 / w1 = m2 * d2 / w2$

here m1 = 10

d1 = 40

m2= ?

d2 = 80

w1 = w2 = 1

substitute,

$10 *40 / 1 = m2 * 80 / 1$

$400 = m2 *80$

$400 / 80 = m2$

5 = m2

Therefore 5 painters complete the same work 80 days
