a person has 1&2 rupee coins with him
total amount with him is 75.total number of coins with him is 50.find how many 1&2 rupee coinsare there with him.

  • mathematics -

    Solve these two equations for x and y:

    x + y = 50

    x + 2y = 75

    (y is the number of 2 rupee coins; x is the number of 1 rupee coins)

    Clearly y = 25, and x is also 25.

  • mathematics -

    he has 25 one rupee coins and 25 two rupee coins together he has 50 coins with total amount of 75 rupees

    1*25+2*25=25+50=75 rupees
