Question

Two computers were purchased for rupees16000 each.one was sold at a gain of 5% and the other at a loss of 4%.find the overall gain or loss% in
The whole transaction

Answer 1

Answer:

CP of computer=16000 rs

no of computer= 2

total cost= 2×16000=32000rs

first is sold at 5% gain ,

gain= (5×16000)/100=800 rs

SP of first computer=800+16000=16800 rs

2nd has loss of 4% ,

loss=(4×16000)/100=640 rs

SP of 2nd computer= 16000-640=15360rs

total CP= 32000 rs

total SP= 15360+16800=32160rs

as SP>CP , there is profit,

profit= 32160-32000= 160

profit %=(160×100)/32000= 0.5%

Answer 2

Answer:

I) CPof the Ist Computer = Spx loo/100+Gain.%=16000x100/105

= Rs15238

2 ) Cp of the 2nd computer = spx 100 / 100-loss%=16ooox loo/96

=Rs16667

Total. Sp=16ooo x2 = 32ooo

Total CP = 15238+16667=31905

Sp>CP, Gain=32000-31905= Rs95

Gain%=95/31905x100 = 0.3%
