@Anil

Equation (1)...X be the age of Dhoni's older brother and Y be Dhoni's age

ReplyDelete2/5X=Y

Equation (2) Y+2=(1/2X+2)

Solution

Substituting Yin Equation =/(2)

2/5X+2=1/2X

4X+20=5X

X(Age of Dhoni's older brother)=10

Substituting X in Equation (1)/(2)

Y(Age of Dhoni)=4

Logic:

ReplyDelete4

Dhoni is 4 years old.

ReplyDeleteHer brother is 10 years old.

dhonis age is 4 and his fathers age is 10

ReplyDelete4 years old

ReplyDeleteFour years. His brother is 10.

ReplyDelete+2 years = Dhoni being 6 and his brother being 12

-2 years = Dhoni being two and his brother being 8
