Question

Ten years ago Nasti was twice the age of Misna. 5 years later Nasti's age became 1 1/2 times the age of Misna. How old are Nasti and Misna now?

Answer 1

Answer: Nasti's age is now 40 years old, while Misna is 25 years old

Step-by-step explanation:

We assume:

N = Nasti

M = Misna

Equation 1

N - 10 = 2x (M - 10)

N - 10 = 2M - 20

N = 2M - 20 + 10

N = 2M - 10

5 + N = 1½ (M + 5)

5 + N = 3/2 (M + 5)

Enter the value N = 2M - 10

5 + 2M - 10 = 3 / 2M + 15/2

2M - 5 = 3 / 2M + 15/2

2M - 3/2 M = 15/2 + 5

4 / 2M - 3 / 2M = 15/2 + 10/2

1 / 2M = 25/2

M = 25/2 x 2

M = 25

N = 2M - 10

N = 2. 25-10

N = 50 - 10

N = 40

So, Age Nasti is now 40 years old, while Age Misna is 25 years old

Hope it helps ✌
