Question

sp of ten candles is same as cp of 12 candles find the gain %​

Answer 1

Answer:

The Gain Percentage = 20%

Step-by-step explanation:

Let the C.P of 1 candle = ₹ 1

Thus,

C.P of 12 candles = ₹ 12

Also,

C.P of 10 candles = ₹ 10

Now, according to the Question,

S.P of 10 candles = C.P of 12 candles

Thus,

S.P of 10 candles = ₹ 12

Hence, we are taking the S.P and C.P of 10 candles.

Profit = S.P - C.P

Profit = S.P of 10 candles - C.P of 10 candles

P = ₹12 - ₹ 10

P = ₹ 2

Now,

Profit % = (Profit/C.P) × 100

P% = (₹ 2/₹ 10) × 100

P% = (1/5) × 100

P% = 20%

OR

Let the C.P of 1 candle = ₹ x

Thus,

C.P of 12 candles = ₹ 12x

Also,

C.P of 10 candles = ₹ 10x

Now, according to the Question,

S.P of 10 candles = C.P of 12 candles

Thus,

S.P of 10 candles = ₹ 12x

Hence, we are taking the S.P and C.P of 10 candles.

Profit = S.P - C.P

Profit = S.P of 10 candles - C.P of 10 candles

P = ₹12x - ₹ 10x

P = ₹ 2

Now,

Profit % = (Profit/C.P) × 100

P% = (₹ 2x/₹ 10x) × 100

P% = (1/5) × 100

P% = 20%

Hence,

The Gain Percentage = 20%

Hope it helped and believing you understood it........All the best

Answer 2

The gain percent is 20%.

Given - SP of ten candles and CP of 12 candles

Find - Profit percentage

Solution - Let the SP of one candle be x. So, SP of ten candles will be: 10x.

Now, CP of 12 candles = 10x.

CP of 1 candle = 10x/12

CP of 1 candle = 0.8x

Profit = (x-0.8x)*100/x

Profit = 0.2x*100/x

Profit = 20%

Hence, the profit was 20%.
