Answer 1

Answer:

Step-by-step explanation:

Given Reshma repays her total loan of Rupees 175000 by paying every month starting with the first installment of Rupees 1500. if he increases the installment by 175 rupees every month what amount would be paid by her in the 21st installment what amount of loan does she still have to pay after 21st installment

We have a = 1500, d = 175, n = 21,  

We know that

  Sn = n/2 (2a + (n – 1) d)

  Sn = 21/2 (2(1500) + (21 – 1)175)

  Sn = 21/2 (3000 + 3500)

   Sn = 21/2 (6500)

   Sn = 68250

So after 21 installments amount paid will be Rs 68250.

Balance amount to be paid will be 175000 – 68250 = Rs 1,06,750

So balance amount to be paid will be Rs 1,06,750
