Question

12 labour take 70 days to complete certain work in how many days 21 labors will complete the same work​

Answer 1

Answer:

Its ratio proportion

Let

the same work complete by 21 workers be x

Hence,

12 /21 = 70/x

.

.... 12x = 21 * 70

12x = 1470

x = 1470/12

x = 122 days

Answer 2

21 labours will complete the same work in 40 days.

Step-by-step explanation:

Since we have given that

Number of labour = 12

Number of days = 70

we need to find the number of days if 21 labours will complete it .

According to question, we get that

$12\times 70=21\times x\\\\\dfrac{840}{21}=x\\\\40=x$

Hence, 21 labours will complete the same work in 40 days.
