$\large\bf\underline \blue {To \: \mathscr{f}ind:-}$

• we need to find the number of girls in school.

$\huge\bf\underline \purple{ \mathcal{S}olution...}$

$\bf\underline{\red{Given:-}}$

• ▶ Number of girls in a school is 50 more than boys.

• ▶ Total number of students is 1070.

${ \blue{ \mathscr{ \underline{Let : - }}}}$

Let the number of boys be x.

$\underline{ \large \red{ \mathscr{\dag\:A \bf{ccourding} \: to \: \mathscr {Q} \bf{uestion} ....}}}$

Number of girls is 50 more than number of boys

If Total number of boys is x.

Then,

Number of girls in school is x + 50.

Total number students in school is 1070.

So,

Total number of students in school = Total number of girls + Total number of boys

↛ x + x + 50 = 1070

↛ 2x + 50 = 1070

↛ 2x = 1070 - 50

↛ 2x = 1020

↛ x = 1020/2

↛ x = 510

So,

• Total number of boys is 510

Total number of girls x + 50

Total number of girls = 510 + 50

• Total number of girls = 560

Answer 2

$\sf{\underline{Question:-}}$

In an school , the number of girls is 50 more than boys . the total number of students is1070 find number of girls.

$\sf{\underline{Solution:-}}$

• Total student = 1070
• let, the number of boys be = m

THEREFORE NUMBER OF GIRL = m + 50

• The equation will be 1070 = m + m + 50

So,

→ 1070 = m + m + 50

→ 1070 - 50 = 2m

→ 1020 = 2m

→ 1020/2 = m

→ 510 = m

$\sf{\underline{Therefore:-}}$

• Number of girl = m + 50
• Number of girl = 510 + 50 = 560
