**Section A**

**Q. Present weight of Saket is 100 kg. He has decided to take a weight loss challenge, during his challenge he can only reduce 2.5 kg in each month. After how many months his weight will be 70 kg?**

**Answer:**

As here. a = 100

d = – 2.5 (As his weight is decreasing by 2.5 kg in each month).

So, an = 70

As, an = a + (n-1)d

=> 70 = 100 + (n -1) * (-2.5)

=> 70 = 100 -2.5n +2.5

=> 2.5 n = 102.5 -70

=> 2.5 = 32.5

=> n=32.52.5 = 13
