Question of the day

Satvik bought some kiwi fruits at a price of 18 kiwi fruits for Rs. 450 and an equal number at a price of 12 kiwi fruits for Rs. 360. He then sold all of these at a price of 10 kiwi fruits for Rs. 300 and earned Rs. 450. Find the the total number of fruits?

    Let total number of fruits of each kind = x

    Cost price of one fruit of first kind = 450 / 18=25
    Total cost price of fruits of first kind = 25x25x

    Cost price of one fruit of second kind = 360 / 12=30
    Total cost price of fruits of second kind = 30x

    Total cost price = 25x+30x=55x

    Selling price of one fruit = 300 / 10=30
    Total selling price = 2x×30=60

    Profit = 60x−55x=5x

    5x=450
    ⇒x=450 / 5=90

    Total no of fruits =2x=2×90=180
