Answer:
51,800 rupees
Step-by-step explanation:
Cost of 5 grams of gold on 1 May 2012 = 14 000 rupees.
The cost of gold decreased by 7.5% from 1 May 2012 to 1 May 2013
Cost of 5 grams of gold on 1 May 2013 = 14,000 - 7.5% of 14,000
= 14,000 - 0.075 × 14,000
= 14,000 - 1,050
= 12,950 rupees
Work out the cost of 20 grams of gold on 1 May 2013
Since, there are four 5 grams of gold in 20 grams of gold
Therefore,
Cost of 20 grams of gold on 1 May 2013 = 12,950 rupees × 4
= 51,800 rupees
