Options:
(A) more than 7
(B) Less than 3
(C) More than 3
(D) Less than 1/3
(E) none of these
Step-by-step reasoning process: Let number of boys = x
Let number of girls = y
Therefore x/y = B and y/x = G
7(B + G) = 7[(x/y) + (y/x)] = 7[(x2 + y2)/xy] > 7
 <hau> Tambayar ita ce: Idan rabo na yara maza zuwa'yan mata a cikin aji shine B kuma rabo na'yan mata zuwa yara maza shine G; to 7 (B + G) shine? Zaɓuɓɓuka: (A) fiye da 7 (B) Ƙasa da 3 (C) Fiye da 3 (D) Kasa da 1/3 (E) babu ɗaya daga cikin waɗannan Mataki-by-mataki tunani tsari: Bari yawan boys = x Bari yawan 'yan mata = y Saboda haka x/y = B da y/x = G 7 ((B + G) = 7 (x / y) + (y / x) = 7 (x2 + y2) / xy) > 7
