एक मशीन ₹18,200 में खरीदी जाती है और इसका मूल्य हर साल 10% घट जाता है। यदि मूल्यह्रास वार्षिक रूप से संयोजित किया जाए, तो 2 वर्ष बाद मशीन का मूल्य क्या होगा?

  • a) ₹14,742
  • b) ₹15,200
  • c) ₹13,424
  • d) ₹16,480
  • a) ₹14,742
  • b) ₹15,200
  • c) ₹13,424
  • d) ₹16,480

correct answer : a)

Explanation :

Value after 2 years = Initial Value × (1 – r/100)² = 18,200 × (0.90)² = 18,200 × 0.81 = ₹14,742.

2 वर्ष के बाद का मूल्य = प्रारंभिक मूल्य × (1 – r/100)² = 18,200 × (0.90)² = 18,200 × 0.81 = ₹14,742।
