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?

Solution

✅ Correct Option: 1

A shopkeeper has pulses worth Rs. 85 per kg and Rs. 100 per kg. The target mixture price is Rs. 92 per kg.

Using the Alligation Method:

Ratio == (Costlier −- Mean) : (Mean −- Cheaper)

Ratio == (100−92):(92−85)(100 - 92) : (92 - 85)

Ratio == 8:78 : 7


The cheaper pulses (Rs. 85) must be taken in larger quantity (8 parts) and the costlier pulses (Rs. 100) in smaller quantity (7 parts) to achieve the mean price of Rs. 92 per kg.


Therefore, the ratio is 8:78:7.
