C. Rs. 16540 C. 16540 টাকা

D. Can't be determined D. নির্ধারণ করা যাবে না

Let the average monthly income of 4 earning members = Rs. 15130.

Total monthly income of 4 members = 4 × 15130 = Rs. 60520.

After one daughter got married and left, the average monthly income of the remaining 3 members = Rs. 14660.

Total monthly income of 3 members = 3 × 14660 = Rs. 43980.

Therefore, the married daughter’s monthly income = 60520 − 43980 = Rs. 16540.

Hence, the married daughter’s monthly income is Rs. 16540.

মোট শুরুতে 4 জনের গড় = 15130 টাকা ⇒ মোট আয় = 4 × 15130 টাকা= 60520 টাকা

কন্যা বের হলে 3 জনের গড় =14660 টাকা ⇒ মোট আয় = 3 × 14660 = 43980 টাকা

অতএব, কন্যার আয় = 60520 − 43980 টাকা= 16540 টাকা

সুতরাং, বিয়ে করা কন্যার মাসিক আয় = Rs. 16540 টাকা
