    A recent survey of married couples in Indian metro

    cities showed that 20% of the couples have only one child, 45% of the remaining couples have two children, and the rest of the couples have three or more children. What is the percentage of couples with three or more children?
    A 44% Correct Answer Incorrect Answer
    B 42% Correct Answer Incorrect Answer
    C 56% Correct Answer Incorrect Answer
    D 35% Correct Answer Incorrect Answer

    Solution

    Total number of couples = 100% So couples having only one child is 20% of 100% = 20/100 x 100 = 20 Remaining 100- 20 = 80 Now couples having two child is 45% of remaining, i.e. 80 x 45% = 80 x 45/100 = 36, Remaining left now = 80% - 36% = 44%.
