Question

A man sold two steel chairs for Rs.500 each. On one he gains 20%, and on the other he loss 12%. How much does he gain or loses in the whole transaction ?

• A. 2.53% (approx)
• B. 1.83% (approx)
• C. 1.53% (approx)
• D. 1.13% (approx)

Answer 1

The correct option is C 1.53% (approx)

Total S.P. = 2 x Rs. 500 = Rs.1000
Total C.P. $=(\frac{500\times 100}{20}+\frac{500\times 100}{80})=Rs.(\frac{120}{3}+\frac{6250}{11})=Rs.\frac{32500}{33}$
$\therefore Gain=1000-\frac{32500}{33}=\frac{33000-32500}{33}=\frac{500}{33}$
$\therefore Gain\%=\frac{\frac{500}{33}}{\frac{32500}{33}}\times 100=\frac{500}{32500}\times 100=1.53\%$ (approx)
