    Solution

    ATQ,

    Let the number of ₹1, 50p, and 10p coins be 6x, 5x and 9x respectively.

    ATQ:

    (6x × 1) + (5x × 0.50) + (9x × 0.10) = 376.60

    Or, 6x + 2.5x + 0.9x = 376.60

    Or, 9.4x = 376.60

    Or, x = 376.60 / 9.4 = 40

    So, number of 10-paise coins = 9x = 9 × 40 = 360
