Question

By selling a radio for Rs. 950, a man loses 5 %. What per cent shall he gain by selling it for Rs. 1040 ?

(a) 4 %

(b) 4.5 %

(c) 5 %

(d) 9 %

Answer 1

Answer : (a)

Sp of a radio = Rs. 950

Loss = 5 %

$\therefore CP=\frac{SP\times 100}{100-Loss\%}=\frac{950\times 100}{100-5}=Rs.\frac{950\times 100}{95}=Rs.1000$

In second case, SP = Rs. 1040 - 1000 = Rs. 40

$\therefore Gain\%=\frac{Totalgain\times 100}{CP}=\frac{40\times 100}{1000}=4\%$
