Question

Raju sells 15 apples for ₹180. How many apples can be bought for ₹372?​

Answer 1

Answer:

Since,12 apples purchased for RS. 10

So, 1 apple purchased for RS. 10÷12

Hence, c.p of 1 apple=5/6=0.833

Again,

Since,10 apples sold for RS. 12

So, 1 apple sold for RS. 12÷10

Hence, sp of 1 apple=6/5=1.2

Since, sp>cp

Hence, gain=1.2–0.833=0.367

And gain%=(gain/cp)×100=(0.367÷0.833)×100= 44% approx.

Answer 2

Answer:

31

180/15 is cost of one apple=12 rupees

number of apples with 372 rupees=372/12=31
