2. Rs.23000
3. Rs.25,000
4. Rs 45,000

Answer 1

Correct Answer - Option 3 : Rs.25,000

Given

Cost of 6 i- pads and 8 laptop = Rs 2,90,000

Cost of 1 i-pad = Rs 15,000

Formula used

Average = Sum of all observation/Number of observation

Calculation

Cost of 6 i-pads = 15000 × 6

⇒ Rs.90,000

Cost of 8 laptops and 6 i-pads = Rs.2,90,000

⇒ 8 laptops + 6 i- pads = 2,90,000

⇒ 8 laptops + 90,000 = 2,90,000

⇒ 8 laptops = 2,00,000

⇒ Laptops = 2,00,000/8

⇒ Laptops = 25,000

∴ Average price of a laptop is Rs 25,000.
