A) \[(i)\to s,(ii)\to p,(iii)\to r,(iv)\to q\]
B) \[(i)\to s,(ii)\to p,(iii)\to q,(iv)\to r\]
C) \[(i)\to p,(ii)\to r,(iii)\to s,(iv)\to q\]
D) \[(i)\to r,(ii)\to s,(iii)\to q,(iv)\to p\]
Correct Answer: C
Solution :
\[(i)\to s,\,\,(ii)\to p,\,\,(iii)\to q,\,\,(iv)\to r\] (i) \[\frac{60}{100}\times x-60=\frac{60}{100}\] \[\frac{60x-6000}{100}=\frac{60}{100}\] \[60x=6000+60=6060\] \[x=\frac{6060}{60}=101\] (ii) \[\frac{2}{x}=\frac{x}{8}\Rightarrow {{x}^{2}}=16,x=4\] (iii) \[27\times C.P.=25\times S.P.\] \[S.P.=\frac{27}{25}C.P.\] \[\text{Profit}%=\frac{S.P.-C.P.}{C.P.}\times 100\] \[=\frac{\frac{27}{25}C.P.-C.P.}{C.P.}\times 100=\frac{2}{25}\times 100=8%\] (iv) \[\frac{50}{100}x+2=7\Rightarrow x=(7-2)\times 2=10\]
