5) Two fifth of the worker in a factory are men. The rest are women.
If there are 28 men, how many more women than men are there?​

Answer 1

Answer:

1) Number of girls = 24

2) Rene  is left with = ₹640

3) Erfen is left with 480 - 288 = 192 apples

4) The product of $\frac{2}{5} and \frac{3}{4}$ = $\frac{3}{10} = 0.3$

5) Number of women more than men in that factory = 14

Step-by-step explanation:

1) A class of 40 pupils.  $\frac{2}{5}$ of them are boys $\frac{2}{5} of 40$ $= 16$

Number of girls = Number of pupils - Number of boys = 40 - 16 = 24

2) Rene had ₹960.  He spent $\frac{1}{3} of 960$ = ₹320

He is left with = ₹960 - ₹320 = ₹640

3) Erfen had 480 apples for sale.  He sold $\frac{3}{5} of 480 = 288$

He is left with 480 - 288 = 192 apples

4) The product of $\frac{2}{5} and \frac{3}{4}$ = $\frac{2}{5}$ x $\frac{3}{4}$ = $\frac{3}{10} = 0.3$

5) Two fifth of the worker in a factory are men = 28

Total number of workers in that factory = $\frac{5}{2}$ x 28 = 70

Total number of women workers in that factory = 70 - 28 = 42

Number of women more than men in that factory = 42 - 28 = 14
