  • SCREEN [2]

    A shopkeeper gives old clothes at rate of ₹90 instead of ₹100
    It can be said that on sale of ₹100 shopkeeper takes ₹10(i.e. ₹100 - ₹90) less
    Dividing 100 in 100 parts we get 1 simliarly on dividing 10 in 100 parts we get 10/100
    Thus for sale of ₹1 shopkeeper takes ₹10/100 less
    Thus for sale of ₹100 clothes the shopkeeper takes (10/100) + (10/100) + ......(100 times)
    Thus shopkeeper gives (10 / 100) * 100 = 10% discount if he sells clothes at ₹90 instead of ₹100
    Thus it can be said that the shopkeeper gives 10% discount on sale of clothes of ₹100

    Similarly if the shopkeeper gives old clothes at rate of ₹10432 instead of ₹41728
    It can be said that on sale of ₹41728 shopkeeper takes ₹31296(i.e. ₹41728 - ₹10432) less

    Dividing 41728 in 41728 parts we get 1 simliarly on dividing 31296 in 41728 parts we get 31296/41728
    Thus for sale of ₹1 shopkeeper takes ₹ 31296/41728 less
    Thus for sale of ₹41728 clothes the shopkeeper takes (31296/41728) + (31296/41728) + ......(41728 times)
    Thus shopkeeper gives (31296 / 41728) * 100 = 75% discount if he sells clothes at ₹10432 instead of ₹41728
