Monthly savings were 4000, 4400, 4840, and 5324.

Step 1: परिवर्तन (Increase) देखें

• 2nd month – 1st month = 4400 − 4000 = 400

• 3rd month – 2nd month = 4840 − 4400 = 440

• 4th month – 3rd month = 5324 − 4840 = 484

यहाँ हम देख सकते हैं कि हर महीने की बढ़ोतरी 10% अधिक हो रही है:

• 400 × 1.1 = 440

• 440 × 1.1 = 484

Step 2: अगले महीनों का अनुमान

• 5th month increase = 484 × 1.1 = 532.4 ≈ 532

• 5th month saving = 5324 + 532 = 5856

• 6th month increase = 532 × 1.1 ≈ 585

• 6th month saving = 5856 + 585 = 6441 ≈ 6442

✅ सही उत्तर: 6442
