Download Solution PDFGiven:
P is 40% less than Q.
Shortcut Trick
40% = 2/5
So, Q is 2/(5-2) × 100 = 2/3 × 100 = 66.66% more than P.
∴ Q is 66.66% more than P.
Calculation:
Let, Q = 100y
So, P = 100y × (100 - 40)/100 = 100y × 60/100 = 60y
Now,
(Q – P)/P × 100 = 40y/60y × 100 = 66.66%
∴ Q is 66.66% more than P.
Additional Information
If A is 20% less than B,
So,
B is 20/(100 - 20) × 100 = 20/80 × 100 = 25% more than A
Similarly,
If B is 25% more than A,
So,
A is 25/(100 + 25) × 100 = 25/125 × 100 = 20% less than B.
