Question

Nikhil has a variety of pulses which weighs
500 kg. He sold 3/4th of them at a price of
Rs. 42 per kg and rest at a certain price. At
what price must he sell the remainder so as
to get the resultant mixture costing 35 per
kg?​

Answer 1

Answer:

14 per kg

Step-by-step explanation:

total weight 500kg

he sold 3/4*500=375

remaining 500-375=125

he sold 375*42=15750

resultant mixture costing means whole mixture 500*35=17500

let x be cost for 2nd mixture

total cost = 1st mixture cost+2nd mixture cost

17500=15750+(125*x)

125*x=1750

x=14
