Aptitude - Profit and Loss - Discussion

They ask how many pics will you buy if the price increases @20%.

1 Rup =100 Pc.

Find the single pic value (100/6=16.66 Pc).
if we increase the price means it affects the single price value so find the single price value after 20% gain or rise of the price.

16.66*(20/100)=3.33,
rising cost 3.33+basicprice (16.66)=19.99,
app=20 Pc for pic.
20*6=120 after adding profit 20%,
for that past price we only buy,
5 pic for 100 pic= 1 rup.
1.20 Pc will need for buy that 6 pic.

S.p = 1
C.P = N*1/6.

Hello everyone.

let me explain more clearly.
given that cost price of 6toffes =1RS.
s.p of 6 toffees = (100+20)/100 *1RS,
=6/5RS.

For 6/5RS =6toffes.
then for 1RS =?
CROSS MULTIPLY THOSE BOTH WE WILL GET AN ANSWER AS 5.

Guys they have asked how toffees he has to sell so that the profit is 20%, so why do you calculate selling price 6/5, all have mentioned selling price of 6 toffees is 6/5 then it means 6 toffees are sold right, where does 5 toffees come?

Please explain me.

CP of 1 toffee= (1/6).
SP to get 20%gain= (1.2x (1/6) ).
How many to sell to get 1 rupee=> 1/SP= (6/1.2) =5.

6--->1re.
X--->20% gain.

6---> 120
X--->100.

So, X = 100 * 6/120 = 5.

@Anandvijay.

How you can take 125?

1*6*100 = 1 x 120,
X=5

Assume for 100 rs he needs 120 including profit. So
100 rs 600 toffees.

Check-in option with which when dividing 120 comes 600/5 = 120.

Logic is that;

He bought toffees 6 for a rupee but he got 20/100 profit means logically the answer should be less than 6.

So, to get less than 6, the answer should be 6 * 100/120 = 5.
