Question 614774
A man bought cashew nuts worth P 210/ Kilo and peanuts at P 130/ Kilo. How many kilos of cashew nuts and peanuts, where in it will become 5 kilos worth P178 per kilo?
.
Let x = amount(kilos) of cashews
then
5-x = amount (kilos) of peanuts
.
210x + 130(5-x) = 178(5)
210x + 650-130x = 890
80x + 650 = 890
80x = 240
x = 3 kilos (cashews)
.
Peanuts:
5-x = 5-3 = 2 kilos
