Let the numbers of men, women and
children are 3k, 2k and k, respectively.
Given, 3k = 90
? k = 30
Number of women = 60
and number of children = 30
Let the men's, women's and children's
wages be ? 5p, ? 3p and ? 2p, respectively.
According to the question,
Total daily wages = ? 10350
? 90 x 5p + 60 x 3p + 30 x 2p = 10350
? p x (450 + 180 + 60) = 10350
? p = 10350/690 = 15
? Daily wages of a man = 15 x 5 = ? 75
We have the important relation, More work, More time (days)
? A piece of work can be done in 6 days.
? Three times of work of same type can be done in 6 x 3
= 18 days
? = 750.0003 ÷ 19.999
? ? ? 750 ÷ 20
? ? ? 375 ? 38
Subtract 20, 25, 30, 35, 40, 45 from successive numbers. So 0 is wrong.
NA
Each previous number is multiplied by 2.
? 8 m shadow means original height = 12 m
? 1 m shadow means original height = 12/8 m
? 100 m shadow means original height = (12/8) x 100 m
= (6/4) x 100 = 6 x 25 = 150 m
Let 8% of 96 = y of 1/25
? (8 x 96)/100 = y/25
? y = (8 x 96 x 25)/100 = 192
Since the principal is not given, so data is inadequate.
