Question

Trupal buys an old Activa for Rs.4700 and spends Rs.800 on its repairs. If he sells the Activa for Rs.5800, what is his gain percent?

A. 5.50 %
B. 5.40 %
C. 5.55 %
D. 5.45 %


Answer : D

Solution:

Net C.P. = Cost + Repairs

= Rs.4700 + 800

= Rs.5500

S.P. = Rs.5800

Now, 5800= 5500(1+0.01p)

=> p = 300/(550×0.01)

= 5.45 %
