Missing: invested Rs. 72000 ratio
Answer:
• Profit earned on gadget :
⇒ Profit = Investment × Profit%
⇒ Profit = 72,000 × 20%
⇒ Profit = 72,000 × 20/100
⇒ Profit = 720 × 20
⇒ Profit = Rs. 14,400
⠀⠀⠀⠀⠀───────────────
Now profit will distribute in the ratio they invested, Let the investment made by Doraemon and Nobita be 4n and 5n respectively.
• Profit made by each :
⇢ Doraemon = Profit × Ratio/Total Ratio
⇢ Doraemon = 14,400 × 4n/(4n + 5n)
⇢ Doraemon = 14,400 × 4n/9n
⇢ Doraemon = 1,600 × 4n/n
⇢ Doraemon = 1,600 × 4
⇢ Doraemon = Rs. 6,400
⠀
⇢ Nobita = Profit × Ratio/Total Ratio
⇢ Nobita = 14,400 × 5n/(4n + 5n)
⇢ Nobita = 14,400 × 5n/9n
⇢ Nobita = 1,600 × 5n/n
⇢ Nobita = 1,600 × 5
⇢ Nobita = Rs. 8,000
∴ Hence, Profit earned by Doraemon and Nobita are Rs. 6,400 and Rs. 8,000 respectively.
