    In a farm, 55% of the plants are tomato plants. The number

    of chili plants is 40% of the tomato plants, and the number of onion plants is 75% of the number of chili plants. If the number of onion plants is 180, what is the total number of plants on the farm?
    A 1091 Correct Answer Incorrect Answer
    B 1720 Correct Answer Incorrect Answer
    C 2620 Correct Answer Incorrect Answer
    D 1700 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let total number of plants on the farm be 100x

    Number of tomato plants = 0.55 × 100x = 55x

    Number of chili plants = 0.40 × 55x = 22x

    Number of onion plants = 0.75 × 22x = 16.5x

    So, 16.5x = 180

    x = 10.91 (approx)

    Total number of plants on the farm = 100x = 1091
