What is the amount that each of them have to bear for the purchase of the phone? Correct Answer Rs. 9,180
Given Sapna and Sneha have Rs. 10,000 and Rs.11,000
They want to buy a common gift for their friend and share the cost equally between the two of them
Cost price of mobile phone = 18,000
The retailer charged an additional 2 percent amount for gift wrapping and delivery
Overall cost of mobile phone = Cost of mobile phone + Delivery charges
Delivery charges = (2 ÷ 100) × 18,000 = Rs 360.
Overall cost of mobile phone = 18,000 + 360
Overall cost of mobile phone = Rs 18,360
Share the overall cost of mobile phone to the Sapna and Sneha equally.
Amount to each of them = Rs 18,360 ÷ 2 = Rs 9,180.
Hence, "Rs 9,180" is the correct answer.
Shortcut Trick
Given cost price Rs 18,000 and additional 2 percent of delivery charge
Taking Rs 18,000 is 100 percentage and additional 2 percent of delivery charge as a 100 % + 2 % = 102 %
100 % = 18000
102 % = ?
(18000 ÷ 100 %) × 102 % = Rs 18,360
Amount to each of them = Rs 18,360 ÷ 2 = Rs 9,180
