26.At what percentage above the C.P. must an article be marked so as to gain 33% after allowing a customer a discount of 5%?
Option: B
Let C.P. be Rs.100
then, S.P. = Rs.133
Let marked price be Rs.x
then, 95% of x = 133
(95/100) * x = 133
x = (133 * 100)/95 = 140
Ans = 40% above C.P.
27.When a producer allows 36% commission on the retail price of his product,he earns a profit of 8.8%.What would be his profit percent if the commission is reduced by 24%?
Option: C
Let the retail price = Rs.100
then, commission = Rs.36
S.P. = Rs.(100 - 36) = Rs.64
given,profit = 8.8%
C.P. = Rs.(100/108.8) * 64 = Rs.1000/17
new commission = Rs.(36 - 24) = Rs.12
new S.P. = Rs.(100 - 12) = Rs.88
gain = Rs.(88 - (1000/17)) = Rs.496/17
gain% = (496/17) * (17/1000) * 100% = 49.6%
