P is 6 times greater than Q then by what per cent is Q smaller than P?

Then, P = 60.

Q is 50 less than P.
Q, % less than P = $\frac{50}{60} \times 100 = 83.33 %$

Alternative Method
10 (Q) == (6 times greater) ==> 60(P) == x%↓(Less than Q) ==> 10 (Q)
Now,
$x = 50 \times 100 60 = 83.33 % " role="presentation" style="outline: none; margin: 0px; padding: 0px; border: 0px; font-variant: inherit; font-stretch: inherit; font-size: 14.157px; line-height: normal; font-family: inherit; vertical-align: baseline; display: inline; text-align: inherit; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; position: relative;"> x = 50 \times 100 60 = 83.33 %$

P is 6 times greater than Q then by what per cent is Q smaller than P?

P is 6 times greater than Q then by what per cent is Q smaller than P?

Explanation

Then, P = 60.
