Q73 of 107 Page 104

In a school, the number of girls is 50 more than the number of boys. The total number of students is 1070. Find the number of girls.

Let x be the number of boys in the school. Then, the number of girls in the school will be x + 50


According to the question,


⇒ x + (x + 50) = 1070


⇒ 2x + 50 = 1070


⇒ 2x = 1070 – 50


⇒ 2x = 1020


⇒ x = 510


So, the number of boys in the school = 510


∴ Number of girls in the school = 510 + 50 = 560
