Question

A hawker bought some guavas at 9 for Rs 4 and sold them at the rate of Rs 7 per dozen. Find his percentage profit or loss.​

Answer 1

Solutions :-

C.P = cost price

S.P = selling price

[ 1 Dozen = 12 Units ]

Given : A fruitseller bought 5 Dozens of bananas at Rs 12 per dozen.

C.P of 12 banana = Rs 12

C.P of 1 banana = Rs 12/12 = Rs 1

5 Dozens banana = 12 × 5 = 60 bananas

C.P of 60 banana = Rs 1 × 60 = Rs 60

Now,

[ 1 score = 20 Units]

Selling price of bananas is Rs 25 per score

S.P of 20 banana = Rs 25

S.P of 1 banana = Rs 25/20 = 1.25

S.P of 60 bananas = Rs 60 × 1.25 = Rs 75

Therefore,

C.P of 5 Dozens bananas = Rs 60

S.P of 5 Dozens bananas = Rs 75

Compare S.P and C.P :-

S.P > C.P

So, Profit

Profit = S.P - C.P

= Rs ( 75 - 60) = Rs 15

Profit% = (profit × 100)/C.P %

= (15 × 100)/60 %

= 1500/60 %

= 25 %

Hence,

His gain is Rs 15

And gain % is 25 %
