A80%

B75%

C70%

D85%

Answer:

A. 80%

Read Explanation:

P, Qയെക്കാൾ അഞ്ച് മടങ്ങ് കൂടുതലാണ്
P=5QP = 5Q
ഇപ്പോൾ Q, Pയെക്കാൾ എത്ര ശതമാനം ചെറുതാണ് എന്ന് കണ്ടുപിടിക്കണം.

വ്യത്യാസം = (P - Q = 5Q - Q = 4Q)

ശതമാനം ചെറുത് (Pനെ അടിസ്ഥാനമാക്കി):


4Q5Q×100=45×100=\frac{4Q}{5Q} \times 100 = \frac{4}{5} \times 100 = 80%
Q, Pയെക്കാൾ 80% ചെറുതാണ്
