1.A man buys an article for Rs.27.50 and sells it for Rs.28.60. Find his gain percent.
Option: A
C.P. = Rs.27.50
S.P. = Rs.28.60
gain = S.P. - C.P.
gain = Rs.(28.60 -27.50) = Rs.1.10
gain% = (gain * 100)/C.P.
gain% = (1.10 * 100)/27.50 = 4%
2.If a radio is purchased for Rs.490 and sold for Rs.465.50, find the loss percent.
Option: B
C.P. = Rs.490
S.P. = Rs.465.50
Loss = C.P. - S.P.
loss = Rs.(490 - 465.50) = Rs.24.50
loss% = (loss * 100)/C.P.
loss% = (24.50 * 100)/490 = 5%
3.Find S.P. when C.P. = Rs.56.25 and gain = 20%
Option: C
S.P. = 120% of C.P. since it is gain
S.P. = Rs.(120/100) * 56.25 = Rs.67.50
4.Find S.P. when C.P. = Rs.80.40 and loss = 15%
Option: C
S.P. = 85% of C.P. since it is loss
S.P. = (85/100) * 80.40 = Rs.68.34
5.Find C.P. when S.P. = Rs.40.60 and gain = 16%
Option: B
C.P. = Rs.(100/116) * 40.60, since it is gain
C.P. = Rs.35
