Answer 1

Answer:

11.=rs 4200

12.=10%

Step-by-step explanation:

For Ist article

Cp of Ist article= rs 3500

gain= 20%

Sp =rs{ 100+gain%/ 100 × Cp}

=rs(100+20/100 × 3500)

=rs(120/100 × 3500)

=rs 4200

For second article

Cp =rs2500

Loss=4%

Sp=rs{100-Loss%/100 ×Cp}

=rs(100-4/100 × 2500)

=rs(100-4/100 × 2500)

=rs(96/100 × 2500)

=rs 2400

total Cp= rs(3500+2500)=rs6000

total Sp=rs(4200+2400)=rs6600

since Sp>Cp i.e there is gain

gain=rs(6600-6000)=rs600

gain% =(gain/Cp × 100) %

=600/6000 × 100

=10%
