Question

a mixture was sold for rs2142at gain of 5percent.at what price should if be sold by gain of 10percent

Answer 1

Answer:

Step-by-step explanation:

sp =2142

gain=5%

cp=100/100+5*2142=2040

sp on desired gain 10%=100+10/100*2040=2244

Answer 2

gain % = sp -cp / cp × 100
5 = 2142 - cp / cp × 100
5 × cp = (2142 - cp )×100
cp = 4284 - 20 cp
21 cp = 4284
cp = 4284 /21
cp = 204 RS.
10% = (sp -cp)/cp × 100
(10 × cp )/ 100 = sp -cp
10 × 204 /100
204/10 + 204 = SP
204 ×11 /10 = sp
224.4 RS = sp
