Question 191303

Let us bisect the two situations,


<font color=blue>During shortage:</font>

Let {{{x}}} = original price = 56 Rs
{{{x+0.56x}}}, raised by 25%
{{{56+0.25(56)}}}
{{{56+14}}}
<font color=blue>70 Rs</font> becomes {{{x[1]}}}



<font color=blue>After Shortage</font>

Let {{{x[1]-0.15(x[1])}}}= new price, lowered by 15%
{{{70-0.15(70)}}}
{{{70-10.5}}}
<font color=blue>59.50 Rs</font>, (Answer)



*If Original Price was increase only by 8% at the beginning of shortage:


{{{56+0.08(56)}}}
{{{56+4.48}}}
<font color=blue>60.48 Rs</font>,  a little bit higher, almost 1 Rs more.



*Conclusion, having increased by 25% and lowering thereafter by 15% has a cheaper price.
