A reduction of 15% in the price of wheat enables a housewife to buy 6 kg more for ₹2,720. The reduced price of wheat per kg (in ₹) is:
Answer & explanation
Correct answer: option 2
Given :-
Price is reduced by 15%
15% = \(\frac{3}{20}\)
Ratio of old : new
price 20 : 17
consumption 17 : 20
( price is inversely proportional to consumption )
ATQ ,
( 20 - 17 ) R = 3R
3R = 6 kg
1 R = 2 kg
Total new consumption is 20 × 2 = 40 kg
Cost price of 40 kg = 2720
Cost price of 1 kg = \(\frac{2720}{40}\) = Rs.68 per kg
