    E Rs. 380 Correct Answer Incorrect Answer

    Solution

    Ratio of the number of coins of denominations Rs. 1 : Rs. 2 : Rs. 10 = 4 : 5 : 3
    Let, the number of coins of Rs. 1, Rs. 2 and Rs. 10 in the bag be 4x, 5x and 3x.
    Since, the total value of Rs. 2 coins in the bag is Rs. 120
    So, value of Rs. 2 coins = 5x ├Ч 2 = 10x
    10x = 120, x = 12
    Therefore, number of Rs. 10 coins in the bag 3x = 36
    So, required value of Rs. 10 coins = 3 ├Ч 12 ├Ч 10 = Rs. 360
