Answer 1

Step-by-step explanation:

simple to solve this we can use tree formula which is used to calculate this method in competitive exams

2000

|

| 10% (1 yr) = 200 -1

| 10% (2nd yr) = 200 -2

| 5% for last half yr = 100

From eq 1

200

| 10% (1 yr) = 20

| 10% (2nd yr) = 20

20

| 5% for last yr = 1

so calculate all outputs

200+200+100+20+20+1

= 541 ans

Note:- There is only one another option to solve this

which is a tree formula
