Question

5 years ago Amit was three times as old as Armaan 10 years later Amit would be twice as old as Armaan how old are they now

Answer 1

LET ARMAAN = X

AND AMIT = Y

5 YEAR AGO

3(X-5) = (Y-5)

==>  3X-15 = Y-5

==> 3X-Y = 10...............(1)

10 YEAR LATER

2(X+10) = Y+10

==> 2X + 20 = Y+10

==> 2X-Y = -10.................(2)

EQ(1) AND (2)

==> 3X-Y = 10

      2X-Y = -10

==> X = 20

PUTTING VALUE OF X IN EQ(1)

==> 3(20)-Y =  10

==> 60-Y = 10

==> Y = 50

SO, AMIT = 50 AND ARMAAN = 20

I HOPE ITS HELPFUL
