​

Answer 1

Answer:

Gain of 8.89%

Step-by-step explanation:

Total CP = Computer + Phone = 18,000 + 10,500 = 28,500

CP of computer = 18000

17% gain on computer = 17% of CP = 0.17 * 18000 = 3,060

Sell price of computer = 18,000 + 3,060 = 21,060

CP of phone= 10500

5% loss on phone = 5% of CP = 0.05 * 10500 = 525

Sell price of phone = 10,500 - 525 = 9,975

Total SP = Computer + Phone = 21,060 + 9,975 = 31,035

Because Total SP is greater than total CP, it was a gain

Total gain = SP - CP = 31,035 - 28,500 = 2,535

% gain = (Gain / CP) * 100 = (2535 / 28500) * 100 = 8.89%

Answer 2

Step-by-step explanation:

(i) Computer :

Cp = Rs 18,000

Loss = 5%

Sp = 18,000 - 5% of 18,000

= 18,000 - 5/100×18,000

= 18,000 - 900

= 17,100

loss = Cp - Sp

= 18,000 - 17,100

= 900

(ii) Mobile phone :

Cp = 10,500

Loss = 17%

Sp = 10,500 + 17% of 10,500

= 10,500 + 1785

= 12,285

Gain = Sp - Cp = 12,285 - 10,500

= 1,785

Total gain = 1785 - 900 = 885
