Question

Find the gain or loss per cent when:

(i) CP = Rs 2400 and SP = Rs 2592
(ii) CP = Rs 1650 and SP = Rs 1452
(iii) CP = Rs 12000 and SP = Rs 12800
(iv) CP = Rs 1800 and SP = Rs 1611

Answer 1

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

Gain% = $\left(\frac{\mathrm{Gain}}{\mathrm{CP}}\times 100\right)$ $=\left(\frac{192}{2400}\times 100\right)$ = $8$

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

Loss% = $\left(\frac{L\mathrm{oss}}{\mathrm{CP}}\times 100\right)$ $=\left(\frac{198}{1650}\times 100\right)=12$

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

Gain% = $\left(\frac{\mathrm{Gain}}{\mathrm{CP}}\times 100\right)=$ $\left(\frac{800}{12000}\times 100\right)=6.66$


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

Loss% = $\left(\frac{L\mathrm{oss}}{\mathrm{CP}}\times 100\right)=$$\left(\frac{189}{1800}\times 100\right)=10.5$
