Question

Dev buys a radio at 3 fraction 4 of it market price and what is his gain percent

Answer 1

Answer:

60%

Step-by-step explanation:

Dev buys it:

3/4 of its marked price

Dev sell it:

20% more than it's marked price

Solution:

Suppose the marked price of the radio is Rs. 100x.

So,

→CP pf radio = (3/4) of MP = (3/4) × 100x = Rs.75x

And

→ SP of radio = 20% more than MP

= (100x × 120) / 100 = Rs. 120x

Then,

→ Gain = SP - CP = 120x - 75x = Rs. 45x

Hence,

→ Gain % = (Gain × 100) / CP

→ Gain % = (45x × 100) / 75x

→ Gain % = 60%

Therefore: 60% is the percentage of Gain
