Given that to find 15 of 80
=> What % of 80 is 15
Let it be 'p'
=> p% of 80 = 15
=>
Therefore, 15 is 18.75% of 80 => 18.75% of 80 = 15
Example::
Now, in the similar way we can find 15% of 80 =?
=> 15x80/100 = p
=> p = 4 x 3 = 12
Therefore, 15% of 80 = 12
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.
