EXPLAINATION:
Q.1) In a co-educational school,45% of the total students are girls,if there are 440 boys in the school, find the number of girls in the school.
SOLUTION-
Let the total number of students be x
ACCORDING TO THE QUESTION
440+(45% of x)=x
440+45/100x=x
x-45/100x=440
100x-45x/100=440
55x/100=440
x=440×100/55
x=800
HERE,TOTAL STUDENTS=800
NUMBER OF BOYS=440
NUMBER OF GIRLS=800-440
=360
THEREFORE, TOTAL GIRLS=360
Q.2)A potato seller sells 70% of the total potatoes and still has 150 kg potatoes left with him,Find the weight of potatoes he had originally.
SOLUTION
Let total weight be x
ACCORDING TO THE QUESTION
x-(70% of x)=150
x-70/100x=150
100x-70x/100=150
30x/100=150
x=150×100/30
x=500
THEREFORE, ORIGINAL WEIGHT OF POTATOES=500kg.

➡️✨Given :-
Number of girls = 45%.
Number of girls = 45%.Number of boys = 55% = 440.
Answer :-
if 55% = 440
if 55% = 440Then 1% = 440/55
if 55% = 440Then 1% = 440/55Then 45% = (440 * 45)/55
if 55% = 440Then 1% = 440/55Then 45% = (440 * 45)/55= 360
if 55% = 440Then 1% = 440/55Then 45% = (440 * 45)/55= 360Number of girls in the school = 360✨
