Question

Find the gain or loss percent, when: (i) C.P. = Rs 4000 and gain = Rs 40. (ii) S.P. = Rs 1272 and loss = Rs 328 (iii) S.P. = Rs 1820 and gain = Rs 420.​

Answer 1

Answer:

(i(i) Given CP = Rs. 4000, gain = Rs. 40 Gain % = {(Gain/CP) x 100) % = {(40/4000) x 100} % = (0.01 x 100) % Gain % = 1% (ii) Given SP = Rs. 1272, loss = Rs. 328 Loss = CP – SP Hence, CP = Loss+ SP = Rs. 328 + Rs. 1272 = Rs. 1600 Loss % = {(Loss/CP) x 100} % = {(328/1600) x 100% Loss % = 20.5% (iii) Given SP = Rs. 1820, gain = Rs. 420 Gain = SP – CP CP = 1820 – 420 = Rs. 1400 Gain % = {(Gain/CP) x 100} % = {(420/1400) x 100 % Gain % = 30%Read more on Sarthaks.com - https://www.sarthaks.com/685672/find-the-gain-or-loss-per-cent-when-i-c-p-rs-4000-and-gain-rs-40-ii-s-p-rs-1272-and-loss-rs-328
