P, Q നേക്കാൾ 40% കുറവാണ്.
Shortcut Trick
40% = 2/5
അപ്പോൾ, Q എന്നത് P നേക്കാൾ 2/(5-2) × 100 = 2/3 × 100 = 66.66% കൂടുതലാണ്.
∴ Q, P നേക്കാൾ 66.66% കൂടുതലാണ്.
കണക്കുകൂട്ടല്:
Q = 100y എന്ന് കരുതുക
അപ്പോൾ, P = 100y × (100 - 40)/100 = 100y × 60/100 = 60y
ഇപ്പോൾ,
(Q – P)/P × 100 = 40y/60y × 100 = 66.66%
∴ Q, P നേക്കാൾ 66.66% കൂടുതലാണ്.
Additional Information
A, B യേക്കാൾ 20% കുറവാണെങ്കിൽ,
അതിനാൽ,
B എന്നത് 20/(100 - 20) × 100 = 20/80 × 100 = A യേക്കാൾ 25% കൂടുതലാണ്.
അതുപോലെ,
B, A യേക്കാൾ 25% കൂടുതലാണെങ്കിൽ,
അതിനാൽ,
A എന്നത് B യേക്കാൾ 25/(100 + 25) × 100 = 25/125 × 100 = 20% കുറവാണ്.
