Question

Some toffees are bought at the rate of 6 for a rupees and sold at 5 for rupee .find the gain percent

Answer 1

Answer:

CP of six toffees = Rs 1

CP of one toffee = Rs 1/6   ----- (1)

SP of 5 toffees = Rs 1

SP of 1 toffee = Rs 1/5          ---- (2)

Comparing (1) and (2)

Taking LCM = 30

1/6 and 1/5 become 5 and 6  in the numerator

Since CP (5) less than SP (6), we conclude that the transaction is profit.

Actual profit = 6-5 = 1

Profit percentage = profit X 100/CP

= 1 X 100/5 = 20%        

Ans: 20%

y-step explanation:

Answer 2

Answer:

20%

Step-by-step explanation:

Cost price of 6 toffees = Re.1

Cost price of 1 toffee = $\frac{1}{6}$

SP of 5 toffees = Re.1

Sp of 1 toffee = $\frac{1}{5}$

Profit = SP - CP

Profit = $\frac{1}{5}-\frac{1}{6}$

Profit = $\frac{1}{30}$

Profit% = $\frac{\frac{1}{30}}{\frac{1}{6}} \times 100$

Profit% = $20\%$

Hence gain% is 20%
