2100 = 2 × 2 × 3 × 5 × 5 × 7 = 2² × 3 × 5² × 7
By the order of operation, we first do the operation in parentheses
( 6 * (2 + 15) ) /3 = (6* 17)/3 = 102 / 3
Then we do the division
Answer = 102 / 3 = 34

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
