(a) neither loss nor gain
(b) 4% loss
(c) 40% gain
(d) 4% gain
The correct answers to the above question in:
Answer: (d)
SP of article = Rs.69
Loss % = 8%
CP = Rs.${100 × 69}/92$ = Rs.75
New SP = Rs.78
Gain % = ${78 - 75}/75$ × 100 = 4%
Using Rule 3,
C.P. = S.P. × $100/{100 - Loss%}$
= ${69 × 100}/{100 - 8}$
= $6900/92$ = Rs. 75
New S.P.= C.P.$({100 + Profit%}/100)$
78 = 75 × $({100 + Profit%}/100)$
7800 = 7500 + 75 Profit%
${7800 - 7500}/75$ = Profit %
$300/75$ = Profit%
Profit% = 4%
