Answer 1

Step-by-step explanation:

If your Question was

"Raju bought 25 glasses for 50 each. He sold 10 of them at 360 each. Five glasses broke. The rest were sold at 390 each. Find the gain or loss per cent."

then,

Now, 25 glasses were bought for Rs.50

so, C.P. = 25 × 50 = Rs.1250

He sold 10 of them for Rs.360

So, S.P of 10 glasses = 360 × 10 = Rs.3600

5 glasses broke so those can't be sold

Now, glasses left = 25 - 10 - 5 = 10 glasses

So, he sold the rest for Rs.390

S.P of rest 10 glasses = 390 × 10 = Rs.3900

So, Total SP = 3900 + 3600 = Rs.7400

Total CP = Rs.1250

Profit = S.P - C.P

P = 7400 - 1250 = Rs.6150

Now, Profit percentage = (P/CP) × 100

P% = (6150/1250) × 100

P% = 492%

If your Question was

"Raju bought 25 glasses for 50 each. He sold 10 of them at 60 each. Five glasses broke. The rest were sold at 90 each. Find the gain or loss per cent."

then,

Now, 25 glasses were bought for Rs.50

so, C.P. = 25 × 50 = Rs.1250

He sold 10 of them for Rs.60

So, S.P of 10 glasses = 60 × 10 = Rs.600

5 glasses broke so those can't be sold

Now, glasses left = 25 - 10 - 5 = 10 glasses

So, he sold the rest for Rs.90

S.P of rest 10 glasses = 90 × 10 = Rs.900

So, Total SP = 900 + 600 = Rs.1400

Total CP = Rs.1250

Profit = S.P - C.P

P = 1400 - 1250 = Rs.150

Now, Profit percentage = (P/CP) × 100

P% = (150/1250) × 100

P% = 12%

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