Question

Answer

Sorry for my bad explanation.

a) Men with spec = 2/7

b) Women with spec = 50

c) Men and women without spec = 94

d) Men with no spec = 1 – 2/7 

                                      =5/7

 

e) Therefore, (b) + (c) will include,

(women with spec) + (women without spec) + (men without spec) = 94 + 50 = 144

This will give us  all the women there and men without spec.

 

f) Since equal amount of men and women, if there is 7 units of men there will be 7 units of women.

At (e), we got all women which is 7 units, and men without spec is 5 units.

Therefore, 7 units +5 units = 144

equal number of men and women can interpreter as 7 unit of men and 7 unit of women in total.

All with no spectacles + All women with spectacles = 7 unit of women (All women) + 5 unit of men

94 + 50 = 144

Therefore, 12 units = 144

                        1 unit = 12

                       2 units = 24

Answer: 24 men wear spectacles.
