    Anjali has enough money to buy either 50 chocolates or

    75 candies. She decides to keep 30% of her money and spends the rest to buy 20 chocolates and some candies. If she buys 'x' candies, find the value of 'x'.
    A 22.5 Correct Answer Incorrect Answer
    B 18.5 Correct Answer Incorrect Answer
    C 32.5 Correct Answer Incorrect Answer
    D 12.4 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the cost of a chocolate and a candy be Rs. 'a' and Rs. 'b' respectively. So, 50a = 75b Or, a : b = 3 : 2 Let a = 3k and b = 2k Total money = 50 × 3k = Rs. 150k Remaining money = 0.70 × 150k = Rs. 105k So, 105k = 20 × 3k + 2k × x Or, 105k = 60k + 2k × x Or, 45 = 2x Or, x = 22.5
