Question

If increasing 20 by p percentage gives the same result as decreasing 60 by p percentage,what is p percentage of 70​

Answer 1

Answer:

35

Step-by-step explanation:

20 + 20% of P = 60 - 60% of p

20 +  20/100 * P = 60 - 60/100 * P

(100 + P)/5 = (300 -3P)/5

3P + P = 300 -100

4P = 200

P = 50

P % of 70

70 x 50/100

35
