(A) Rs. 222.50              (B) Rs. 267
(C) Rs. 222                   (D) Rs. 220
Answer: C
Solution: Let the cost price (CP) of an article be C
Since there is a loss of 11%,
Therefore, SP = C – 11C/100  = 89C/100
By the problem, 89C/100 = 178
 or, C = 178 × 100/89 = 200
therefore, The cost price (CP) of the article = Rs. 200
He should earn a profit of 11 %
therefore, Sell Price (SP) of the article = C +11C/100
= 200 +11× 200/100
 = 222
