Question

2. Sum of the present ages of Pintu and Mintu is 31. Mintu's age 3 years ago was 4
times the age of Pintu. Find their present ages.​

Answer 1

Answer:

age of pintu = 8 years

age of mintu = 23 years

Answer 2

Answer:

8 years & 23 years, respectively.

Step-by-step explanation:

Pintu' Present age = P

Mintu' s Present age = M

According to the question, P + M = 31 ....1)

Now,

Mintu's age 3 years ago = M - 3

Pintu's age 3 years ago = P - 3

According to the question, M - 3 = 4(P - 3) ....2)

From 1), we know that M = 31 - P

So, by substituting the value of M in 2), we get that,

31 - P - 3 = 4(P - 3)

28 - P = 4P - 12

5P = 40

P = 8

& M = 23
