Answer:
Information given in question :
The profit earned by a vendor by selling bananas at a gain of 10% is ₹30 more than when he sells it a loss of 10%
What we have to calculate :
The cost price of bananas
Assumption :
Let the Cost price of bananas = x Rs
According to the question :
\rm \implies \: \dfrac{110 \: x}{100} - \dfrac{90 \: x}{100} = 30 \implies \: \dfrac{20 \: x}{100} = 30⟹100110x−10090x=30⟹10020x=30
\rm \implies x = \dfrac{30 \times 100}{20}⟹x=2030×100
\rm \implies x = \dfrac{3000}{20}⟹x=203000
\bf \implies x =150 \: Rs⟹x=150Rs
