In a school there are total 414 students. The ratio of boys and girls is 5 : 4. If 46 more boys gets admitted into the school, then what will be the new ratio of boys and girls?
Answer & explanation
Correct answer: option 4
Boys : Girls
5 : 4
⇒ (5 + 4) units = 414
⇒ 9 units = 414
⇒ 1 unit = 46
⇒ Boys = 5 x 46 = 230
⇒ Girls = 4 x 46 = 184
⇒ 46 Boys admitted to the school = 230 + 46 = 276
⇒ New Ratio of Boys and Girl = 276 : 184 = 3 : 2.
