A trader bought 100 tubers at 5 for N350.00. She sold them in sets of 4 for N290.00. Find her gain percent.
3.6%
3.5%
3.4%
2.55
Correct answer is A
Cost price, c.p = 1005 x N350 = N7000
Selling price, s.p = 1005 x N290 = N7250
%Gain = S.p−C.pC.p x 100%
= 7250−70007000 x 100% = 250×1007000
= 3.6% (approx.)
