A) Rs. 200
B) Rs. 255
C) Rs. 400
D) Rs. 433
Correct Answer: B
Solution :
1st payment = 90% of 90% of 70% of Rs. 10000 |
= Rs. \[\left( \frac{90}{100}\times \frac{90}{100}\times \frac{70}{100}\times 10000 \right)\]= Rs.5670 |
2nd payment = 60% of 95% of 95% of Rs. 10000 |
= Rs. \[\left( \frac{60}{100}\times \frac{95}{100}\times \frac{95}{100}\times 10000 \right)\]= Rs. 5415 |
By choosing the better one he can save |
Rs. \[(5670-5415)\] = Rs. 255 |
