Answer» <U>S O L U T I O N : $\underline{\bf{Given\::}}$ The number of boys & GIRLS in a class are in the ratio 7:5. The number of boys is 8 more than the number of girls. $\underline{\bf{Explanation\::}}$ Le the number of boys are in the ratio be 7r & LET the number of girls are in the ratio be 5r respectively . Boys = 7r Girls = 5r A/q $\mapsto\tt{7r=5r + 8}$ $\mapsto\tt{7r-5r =8}$ $\mapsto\tt{2r =8}$ $\mapsto\tt{r=\cancel{8/2}}$ $\mapsto\bf{r=4}$ Now; Number of boys = 7r = 7 × 4 = 28 boy's .

The number of boys and girls in a class are in the ratio 7:5. The number of boys is 8 more than the number of girls. What is the total class strength?please tell friends

Answer»

<U>S O L U T I O N :

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

The number of boys & GIRLS in a class are in the ratio 7:5. The number of boys is 8 more than the number of girls.

$\underline{\bf{Explanation\::}}$

Le the number of boys are in the ratio be 7r & LET the number of girls are in the ratio be 5r respectively .

Boys = 7r
Girls = 5r

A/q

$\mapsto\tt{7r=5r + 8}$

$\mapsto\tt{7r-5r =8}$

$\mapsto\tt{2r =8}$

$\mapsto\tt{r=\cancel{8/2}}$

$\mapsto\bf{r=4}$

Now;

Number of boys = 7r = 7 × 4 = 28 boy's .
Number of girls = 5r = 5 × 4 = 20 girl's .

$\mapsto\sf{Total\:_{(class\:<klux>STRENGTH</klux>)} = No.\:of\:boys + No.\:of\:girls }$

$\mapsto\sf{Total\:_{(class\:strength)} = 28 + 20}$

$\mapsto\sf{Total\:_{(class\:strength)} = 48\:student's}$

Thus;

The total class strength is 48 students .

Answer»

Answer:

14.

Step-by-step EXPLANATION:

According to question:-

2X/3 - X/4 =50

= (8X - 3X) /12= 50

(L.c.m of 3 & 4= 12)

5X =12(50)

5X = 600

X= 600/5

X=120

Hence, the REQUIRED number is 120

[Something to remember]

Two-third= 2/3

One-fourth = 1/4

Of = MULTIPLY

/ = Division
