In what ratio a grocery shopkeeper mix two varieties of pulses worth Rs. 85 per kg and Rs. 100 per kg respectively, so as to get a mixture worth Rs. 92 per kg?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 8 : 7
Let the ratio of mixing be x : y
Price of first variety = Rs. 85/kg
Price of second variety = Rs. 100/kg
Price of mixture = Rs. 92/kg
Using alligation method:
Difference of second price and mixture = 100 - 92 = 8
Difference of mixture and first price = 92 - 85 = 7
Ratio of first to second variety = 8 : 7
