Question

Kirti's brother is 4 years elder to her. 8 years later, the sum of their ages will be 100 years. How old is Kirti now?

Answer 1

Answer:

40yr

Step-by-step explanation:

Let kirti age x his brother age x+4

After 8yr

(x+8)+(x+4+8)=100

x=40yr

Answer 2

Answer:L

Let kirti's age be x

So her brothers age is x+4

x+8(x+4)+8=100

2x+8+4+8=100

2x+20=100

2x=100-20

2x=80

X=80÷2

X=40

Kirti's age is 40 now
