Explanation :   Solution: Let C.P. of whole be Rs. X. C.P. of 1/2 stock = Rs. x/2, C.P. of 1/4 stock = Rs. x/4.   Total S.P. = Rs.[(110% of x/2)+(90% of x/4)+x/4] = Rs. (11x/20 + 9x/40 + x/4)   = Rs. 41x/40.   Gain = Rs. (41x/40 - x) = Rs. x/40.   .'. Gain% = (x/40 * 1/x * 100)% = 2.5%   2.5% gainnswer : 2.5% gain
