Given:
- Average cost of 32 different mobiles = Rs. 9000
- Oppo is costliest and is 70% higher than the cheapest mobile Lava
- Excluding Oppo and Lava, the average cost of remaining mobiles = Rs. 8880

To find: Cost of Oppo mobile

Approach:
1. Find the cost of Lava mobile
2. Use the cost of Lava mobile to find the cost of Oppo mobile
3. Verify the solution

Calculation:
1. Let the cost of Lava mobile be x
- As Oppo is 70% higher than Lava, the cost of Oppo = x + 0.7x = 1.7x

2. Excluding Lava and Oppo, there are 30 mobiles with an average cost of Rs. 8880
- Total cost of these 30 mobiles = 30 * 8880 = Rs. 266400
- Total cost of all 32 mobiles = 32 * 9000 = Rs. 288000
- Cost of Lava + Cost of Oppo = Total cost of all mobiles - Total cost of 30 mobiles
- x + 1.7x = 288000 - 266400
- 2.7x = 21600
- x = 8000 (Cost of Lava)
- Cost of Oppo = 1.7x = 1.7 * 8000 = Rs. 13600

3. Verify the solution
- Total cost of all 32 mobiles = 31 * 8880 + 13600 + 8000 = 288000
- Average cost of all 32 mobiles = Total cost of all mobiles / Number of mobiles = 288000 / 32 = Rs. 9000 (matches the given average cost)

Therefore, the cost of Oppo mobile is Rs. 13600 (option D)
