Step : 1
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 ₹3104 instead of ₹12416
It can be said that on sale of ₹12416 shopkeeper takes ₹9312(i.e. ₹12416 - ₹3104) less
Dividing 12416 in 12416 parts we get 1 simliarly on dividing 9312 in 12416 parts we get 9312/12416
Thus for sale of ₹1 shopkeeper takes ₹ 9312/12416 less
Thus for sale of ₹12416 clothes the shopkeeper takes (9312/12416) + (9312/12416) + ......(12416 times)
Thus shopkeeper gives (9312 / 12416) * 100 = 75% discount if he sells clothes at ₹3104 instead of ₹12416
