Mr.Tandon purchased a computer for ₹ 32,000 and a microwave oven for ₹ 6,500. On computer he lost 5% and on microwave he gained 15%. Find his total gain or loss per cent.(7th class math)
Loss % = 5%
Cost price(C P) of Oven = Rs.6500
Gain % = 15%
(1)Computer:
Loss (Computer) Rs. = 5 % of 32000
= 5/100 X 32000
= Rs.1600
then Selling price of Computer = (32000 - 1600)Rs.
= Rs.30400
(2)Oven:
Gain(Oven) Rs. = 15% of 6500
= 15/100 X 6500
= Rs.975
then Selling price of Oven = (6500 + 975) Rs.
= Rs.7475
Total C P of (computer + oven) = Rs.32000 + Rs.6500
= Rs.38500
Total S P of (computer + oven) = Rs.30400 + Rs.7475
= Rs.37875
S P < C P ,then there is a loss.
Loss% = (C P - S P)/C P X 100
= (38500 - 37875)/38500 X 100
= 625/38500 X 100
= 625/385
= 1.62%
Therefore Loss 1.62%.
