A) 36	B) 34	C) 38	D) 32	E) 31
Explanation :   Let us consider, Ribbon is denoted by r   Clips is denoted by c   Soaps is denoted by s   Now according to the question,   =&gt; 3r+7c+s = 120 -------- (1)   =&gt; 4r+10c+s = 164 -------- (2)   (1) - (2)   =&gt; (3r-4r) + (7c - 10c) +(s - s) = 120 - 164   =&gt; -r - 3c = - 44   Multily the equation by -1 , it becomes   =&gt; r + 3c = 44 ------- (3)   Now Perform this operation 2 * (1) - (2)   =&gt; 2r+4c+s=76 ------- (4)   Finaly (4) - (3)   =&gt; r + c + s=32   Hence, the cost of 1 ribbon ,1 clip and 1 saop would be 32 rs.   Answer : 32
