(i) CP = Rs.620 and SP = Rs.713
Since SP is more than CP. So, it is a case of Gain.
Gain = SP- CP
= 713 - 620
= 93
\(Gain\%=\frac{Gain\times100}{CP}\)
= \(\frac{93\times100}{620}\)
= 15%
(ii) CP = Rs.675 and SP = Rs.630
Since CP is more than SP. So, it is a case of Loss.
Loss = CP- SP
= 675 - 630
= 45
\(Loss\%=\frac{Loss\times100}{CP}\)
\(=\frac{45\times100}{675}\)
= 6.66%
(iii) CP = Rs.345 and SP = Rs.372.60
Since SP is more than CP. So, it is a case of Gain.
Gain = SP- CP
= 372.60 - 345
= 27.60
\(Gain\%=\frac{Gain\times100}{CP}\)
\(=\frac{27.60\times100}{345}\)
= 8%
(iv) CP = Rs.80 and SP = Rs.76.80
Since CP is more than SP. So, it is a case of Loss.
Loss = CP- SP
= 80 – 76.80
= 3.20
\(Loss\%=\frac{Loss\times100}{CP}\)
\(=\frac{3.20\times100}{80}\)
= 4%
