To find the answer, we calculate the total work:

42 women x 18 days = 756 woman-days

Since the work remains the same, we divide the total work by 21 days:

756 woman-days ÷ 21 days = 36 women

So, 36 women can do the same work in 21 days.

Explanation

2994 ÷ 14.5 = 172

We can cross-multiply to get:

2994 × 14.5 = 172 × 100 (multiplying both sides by 100)

Then, we can convert the percentages to decimals by multiplying both sides by 0.01:

29.94 × 145 = 1720

Finally, we can divide both sides by 100 to get:

29.94 × 1.45 = 1720 ÷ 100

= 17.2

Explanation

Let x be volume of the solution

 8/100 × x = 15.

8/100 = 15/x. Cross multiplication.

8x = 15×100.

x = 15 × 100/8.

= 187.5 ml.
