Correct Answer: B

Solution :

We have,         = Rs. 1290    or 1 Bangle = Rs. \[1290~-2\]Necklaces ?..(i)   Now,  = Rs. 1020    or 2( Rs. \[1290~-2\] Necklaces)  + 1 Necklace = Rs. 1020              (from (i))  \[\Rightarrow \] \[2580-4\]Necklaces + 1 Necklace = Rs. 1020  or 3 Necklaces = Rs. 1560    \[\Rightarrow \]1 Necklace = Rs. 520 Since, 1 Bangle = Rs. \[1290-2\]Necklaces \[\therefore \]1 Bangle = Rs. \[\left( 1290-1040 \right)\]= Rs. 250 As we have,   = Rs. 890 \[\therefore \]1 Earring = Rs. 890 \[-\] (1 Necklace + 1 Bangle) \[=890-770=\] Rs. 120 Now,   = Rs. 550 or 1 Ring = Rs. 550 - (1 Bangle + 1 Earring) = Rs. 550 - 370 = Rs. 180
