Mr Tandon purchased a computer for 32,000 and a microwave oven for 6500 on computer he lost 5% and microwave he gain 15% find his total gain or loss percent

Answer 1

Hope it helps...!!!!

______________

Cost price of computer => Rs. 32000

Loss incurred => 5%

Selling Price=>CP(100g+g/100)

=>6500(100+15/100)

=>6500×115/100

SP of oven=> Rs. 7475

Total cost price => Rs 32000 + Rs 6500 = Rs 38500

Total selling price => Rs 30400 + Rs 7475 = Rs 37875

Here SP < CP

Hence Mr. Tandon gets loss

Loss => Rs 38500 – Rs 37875 => Rs 625

Loss percent => (625 / 38500) × 100 => 1.62% (nearly)

Answer 2

$\huge\bold\red{Hey}$

CP of computer = Rs.32000

Loss percent = 5 percent

SP of computer = 32000×(100-5)/100

= 32000×95/100

= Rs. 30400

CP of microwave oven = Rs. 6500

Gain Percent = 15 percent

CP of microwave oven = 6500

(100+15)/100

= 6500×115/100

= Rs. 7475

Total CP = Rs. (32000+6500)

= Rs. 38500

Total SP = Rs. (30400+7475)

= Rs. 37875

SP < CP

Loss = Rs. (38500-37875)

= Rs. 625

Loss Percent = 625/38500×100

= 125/77 Percent

= 1.62 Percent
