The C.P. is increased by 20% but the S.P. remains constant.
To Find : For a weight of 12 kgs how much the trader should
weigh so that he is having the same percentage profit?
(a) 15 kg (b)10 kg (c) 8 kg
(d) 14.4 kg (e) 9 kg
Solution:
The C.P. of an article is Rs.x
a weight of 12 kgs
CP = 12x
SP = 12y
Profit % = 100 * ( 12y - 12x)/12x = 100 (y - x)/x
C.P. is increased by 20%
New CP = 12x + (20/100)12x = 14.4x
New SP = 14.4x + 14.4x(100 (y - x)/x) /100
= 14.4x + 14.4y - 14.4x
= 14.4y
Hence to be weighed = 14.4y/y = 14.4 kg
