Some articles were bought at 6 articles for Rs. 5 and sold at 5 articles for Rs. 6. Gain percent is ?
A. 30 %
B. 33 1/3 %
C. 35%
D. 44%
Answer : D. 44%
Explanation:
Suppose, number of articles bought = L.C.M. of 6 and 5 = 30
Cost Price (C.P) of 30 articles = Rs.( 5 / 6 ) x 30
= Rs. 25
Selling Price (S.P) of 30 articles = Rs.( 6 / 5 ) x 30
= Rs. 36
Gain % = ( 11 / 25 ) x 100%
= 44%
