P is 6 times greater than Q then by what per cent is Q smaller than P?
Answer & Solution
Correct Answer:
Option
D
Let Q = 10.
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,
$${\text{x}} = \frac{{50 \times 100}}{{60}} = 83.33\% $$
Now,
$${\text{x}} = \frac{{50 \times 100}}{{60}} = 83.33\% $$

100......100/6
Q is smaller=100-100/6=83.333333
You r wrong...
Here 6 times greater not more 6 times
So,6x....Not 7x
SO, A= x + 6x,
ATQ,
B-A = 6x
(6x/7x )* 100 = 85.71 %
