Answer:

given,

selling price (sp)=rs 5 ×30

=rs 150

now, gain %=20%

cost price (cp)=


(sp * 100)/(100 + gain\%)


= (150 * 100)/(100 + 20)

therefore cp= rs125

now,

again in 2nd case

sp= rs 27×5

therefore sp=rs 135

and cp= rs125

now, sp>cp so,


gain\% = (sp - cp)/(cp) * 100\%

or, gain=


= (135 - 125)/(125) * 100\%

therefore gain %= 8%.... is answer

hope it helps..
