Answer 1

hello friend...♥♥
your answer is here⏬⏬

by shortcut method:-
SP = Rs. 840

if gain = 20%
gain% = (SP-CP)/CP * 100
⇒ 20= (840-CP)/CP * 100
⇒ 20/100 = (840-CP)/CP
⇒ 0.20CP = 840 - CP
⇒ 0.20CP + CP = 840
⇒ CP = 840/1.2 = Rs. 700

if loss = 20%
loss% = (CP-SP)/CP * 100
⇒ 20 = (CP-840)/CP * 100
⇒ 20/100 = (CP-840)/CP
⇒ 0.20CP = CP - 840
⇒ CP - 0.20CP = 840
⇒ CP = 840/0.8 = Rs. 1050

Total CP = 700+1050 = 1750
Total SP = 840+840 = 1680

loss = 1750- 1680= Rs. 70
loss% = loss/CP * 100 = 70/1750 * 100=4%.

this is an example....

but i hope it helps u....❤✔
