1. M is a girl and has the same number of brothers as sisters. N is a boy and has twice as many sisters as brothers. M and N are the children of Q. How many children does Q have?

  • A. 2
  • B. 2
  • C. 2
  • D. 2

Answer: Option B

Explanation:

M ছাড়া 3 জন sister এবং 3 জন brother হয়। আবার N ছাড়া 2 জন brother এবং দ্বিগুণ বোন মানে 4 জন sister হয়।
অর্থাৎ M + 3 জন sister + 3 জন brother = 7 জন
N + 4 জন sister + 2 জন brother = 7 জন
সুতরাং Q এর children মোট 7 জন।
