Question

A shopkeeper gives 3 chocolates fr 1rupee. for every 3 rappers that you return he gives 1 more chocolate. so for 45 rupees how many chocolates u can get ??

Answer 1

A shopkeeper gives 3 chocolates for 1 rupee n if u return 3 rappers he would give u another chocolate. Therefore he gets 4 chocolates for 1 rupee and for 45 rupees he should get 45x4 = 180 chocolates if he returns 3 rappers for 1 rupee but If he gives back all the rappers which he have then he should get 45/3 = 15 chocolates more (as for 3 rappers 1 chocolate is given)
Therefore he should get 180 + 15 = 195 chocolates
