Answer 1

Step-by-step explanation:

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
