Question

Two varieties of pulses at ` 50/kg and ` 80/kg are mixed together in the ratio 4 : 5. Find the average price
of the resulting mixture.

Answer 1

Heya User,

--> Ratio of Pulse [ Rs. 50/kg ] = [ 4 ] / [ 4 + 5 ]  = 4 / 9
--> Ratio of Pulse [ Rs. 80/ kg ] = 5 / 9

=> Average Price of Mixture = ( 4 / 9 ) * 50 + ( 5 / 9 ) * 80
                                                = ( 200+ 400 ) / 9
                                                = 200 / 3 = Rs. 66.66 

Hence, avg. price is 66 rupees 66 paise √√
