Answer 1

i. ₹5000

ii. ₹105000

iii. ₹5250

iv. ₹110250

Explanation:

`X\ represents\ the\ times\ symbol.`

i.

`100000\ X ((10)/(100\ X\ 2))^(1) \ \ for\ 6\ months\\= 5000`

ii.

`100000+5000=105000`

iii.

`100000\ X (1+(10)/(100\ X\ 2))^(2) \ \ for\ 12\ months\\= 110250\\\\110250-100000-5000=5250`

iv.

`110250`
