Question

Vishnu is three times as old as his sister Nalini, Three years ago, he was two years less than four times the age of his sister. Find their present age​

Answer 1

Answer:

Step-by-step explanation:

and, x-3+2 = 4(y-3)

                      x-1 = 4y-12

                  so, x-4y = -11

     By Eqn (1),   3y-4y = -11

                          so, y = 11

                   so, x = 33

Answer 2

Answer:

$x - 3 + 2 = 4(y - 3) \\ x - 1 = 4y - 12 \\ so.x - 4y = - 11 \\ 3y - 4y = - 11 \\ y = 11 \\ then.x = 33$

Hope it's help you!!!
