Answer 2

Answer:

(i) 8

(ii) 12

(iii) 6.66

(iv) 10.5

Step-by-step explanation:

(i) CP = Rs. 2400  

(i) CP = Rs. 2400  SP = Rs. 2592

Gain = SP - CP = Rs. ( 2592 - 2400) = Rs. 192

$gain\% = gain \\ \: \: \: \: \: \: \: \: \: \: \: cp \: \times 100$

$192 \\ \: 2400 \times 100 \: = 8$

(ii) CP = Rs. 1650  

(ii) CP = Rs. 1650  SP = Rs. 1452

(ii) CP = Rs. 1650  SP = Rs. 1452    Loss = CP - SP = ( 1650 - 1452) = Rs. 198

LOSS٪ = Loss / CP ×100

= 198 / 1650 ×100= 12

(iii) CP = Rs. 12000   and   SP = Rs. 12800

(iii) CP = Rs. 12000   and   SP = Rs. 12800    Gain = SP - CP = ( 12800 - 12000) = Rs. 800

(iii) CP = Rs. 12000   and   SP = Rs. 12800    Gain = SP - CP = ( 12800 - 12000) = Rs. 800   

Gain% = Gain / CP ×100

800/12000×100=6.66

(iv) CP = Rs. 1800  

(iv) CP = Rs. 1800  SP = Rs. 1611

(iv) CP = Rs. 1800  SP = Rs. 1611     Loss = CP - SP = ( 1800 - 1611) = Rs. 189

Loss% = Loss/CP×100

189/1800×100= 10.5
