Question

if 10 men finish a work in 12 days how many days required for 15 men to finish the job

Answer 1

Step-by-step explanation:

with 10 men, time= 12 days

so with 1 man, time=

$\frac{12}{10}$

So work for 1 man is 10/12

so work for 15 men will be 15× 10/12

=75/6

So time taken = 6/75=0.08 days

Answer 2

Answer:

8 days

Step-by-step explanation:

If p and q are inversely proportional, p times q is any constant k.

Here first value of p is 10 and first value of q is 12.

P times q i.e 10 times 12 is a constant 120.

Now, second value of p is 15 and second value of q is x.

That is, 10 times 12 = 15 times x

120 = 15x

x = 120/15

Therefore, x is 8 i.e it will take 8 days for 15 men to finish the work .

Hope it helped you!
