A reduction of 20% in the price of bananas enables a customer to buy 6 more bananas for ₹80. What is the reduced price of bananas per dozen (in ₹)?
Answer & explanation
Correct answer: option 1
Reduction in price = 20%
Ratio of old : new
price 5 : 4
quantity 4 : 5
(We know , Price is inversely proportional to quantity bought .)
ATQ ,
( 5 - 4 ) R = 1R
1R = 6
New quantity bought = 6 × 5 = 30 bananas
= 2.5 dozen ( 12 banana = 1 dozen )
Price of 2.5 dozen = 80
Price per dozen = \(\frac{80}{2.5}\) = 32 Rs/dozen
