hi

answer

2500*85*80*90*95/100/100/100/100=1453.5 rs the customer will pay on the succesive discount offer

now directly he will pay

2500*50/100=1250 rs

so amount extra paid =1453.5-1250=203.5 rs

  Hi Mohit smile

Let the initial amount be 100 on which discounts are offered. After a discount of 6%, we are left with 94. Further discount of 15% means deduction of 9.4 + 4.7 = 14.1 i.e. remaining amount is 94 - 14.1 = 79.9. And after third discount of 10%, the remaining amount is = 79.9*0.9 = 71.91. So the final (single) discount availed is = 100 - 71.91 = 28.09 %.

There is no need to find the exact HCF in this case. You can directly check with the options easily. (Answer option + 8) must be the HCF of the three numbers. And it can be easily checked that 15 + 8 = 23 doesn't divide 231, 10 + 8 = 18 doesn't divide 189 and 21 + 8 = 29 also doesn't divide any of them.
So answer will be d.
